This quick and easy Grilled Mexican Quesadilla Recipe With Lentils is a tasty dinner for meatless Mondays!

One of my kids’ favorite school-night meals is quesadillas. I can certainly see why. Quesadillas are one of those timeless comfort foods—warm, cheesy, and satisfying. It’s basically a grilled cheese in a tortilla, depending on how you make it, though I like to sprinkle some homemade fajita seasoning for extra flavor. I’ll add other ingredients like chicken for extra protein and refried beans for fiber. However I make these quesadillas, my kids love to eat them up!
Once in a while, I’ll stretch the boundaries just to see if I can sneak in other nutritious add-ins, like lentils. Much to my surprise, the kiddos don’t even notice. Lentils have a mild, earthy flavor, but you can’t tell because of all the Mexican cheese. And with a sprinkle of fajita seasoning (or taco seasoning), it’s practically impossible for my picky eaters to detect a hint of these fibrous legumes.

Plus, making these quesadillas is as simple as it gets. The only curveball here is with the lentils, but those extra steps are worth it. Blending the cooked lentils with your salsa of choice really amps up the flavor!
Whether you’re a fan of spicy salsa or prefer mild with some creamy guacamole, these quesadillas go with all the standard toppings. And with a crisp, golden tortilla exterior straight off the grill (or pan!), they give a restaurant-like taste—eat your heart out, Chili’s!

Are Grilled Mexican Quesadillas with Lentils Healthy?
Lentils are a powerhouse of plant-based nutrition, offering a decent dose of protein, fiber, and essential minerals like iron. You also get some calcium from the cheese, though it’s not a mind-blowing amount. To make the quesadillas even lighter, you can swap regular cheese for a lower-fat option. Personally, I’d just reduce the regular amount slightly because low-fat cheese doesn’t melt as nicely. If you need a gluten-free alternative, try corn tortillas instead. The texture is different, but they taste pretty great grilled!

Grill, Skillet, or Pan—What’s the Difference?
When it comes to making the perfect quesadilla, your cooking method affects both the taste and texture of your tortilla. A grill, especially a charcoal grill, offers an unbeatable smoky flavor and crisp edges. The high heat gives the quesadilla a deliciously golden finish while melting the cheese to perfection. It’s my favorite method by far, but you definitely need to keep an eye on your grill—your quesadilla will get done faster than you think.
Next in line is the skillet, which is typically made from cast iron or stainless steel. They’re known for their durability and ability to retain heat. Cast-iron skillets, in particular, are great for creating that perfect golden crust because they distribute heat evenly and can handle higher temperatures.
Then there are nonstick frying pans. These are often lighter than skillets and coated with Teflon or ceramic to prevent sticking. They’re perfect for cooking delicate foods or when you want an easy cleanup, but they generally don’t achieve the same level of crispness or browning as a cast-iron skillet.
Any of these options work for quesadillas, but if you can, try this recipe on your grill!

How to Make Ahead and Store
You can prep the lentil purée up to 2 days ahead and store it in an airtight container in your fridge. As for the assembled quesadillas, they’re best grilled fresh—I wouldn’t make these in advance. However, you can refrigerate leftovers for up to 4 days. To reheat, use a skillet, oven, or even an air fryer. I’ve found that air fryers crisp up quesadillas the best. They taste almost as good as the day you made them!
Serving Suggestions
These quesadillas are delicious on their own, but they shine with the right sides. Serve them with extra Salsa, guacamole, or sour cream for dipping. If you’re planning a full Mexican-inspired meal, pair them with Mexican Brown Rice for a whole-grain take on a classic. Watching your carbs? This Cilantro-Lime Cauliflower Rice is a delicious alternative. Or try this refreshing Mexican Grilled Corn Salad With Jalapeño And Avocado. It’s quite flavorful and packs a little heat, a perfect complement to the cheesy quesadillas.
Recipe
Ingredients
- 1/2 cup green lentils
- 1 1/2 cups water
- 1/2 cup salsa divided
- 1/8 teaspoon salt
- 8 extra-large white corn tortillas (6 inches)
- Olive oil spray
- 1/2 cup cilantro roughly chopped
- 1 1/3 cups Mexican blend cheese (5 ounces)
- Sour cream (for serving, optional)
- Guacamole (for serving, optional)
Instructions
- Rinse the lentils, place them in a medium pot with the water, and bring to a boil.
- Once boiling, turn the heat to medium-low, cover, and cook until tender, about 15-20 minutes. Drain and transfer to a food processor.
- Add 1/4 cup of the salsa and salt into the food processor and pulse until combined and smooth, but leaving some lentils intact for texture.
- Preheat your grill to medium.
- Spray one side of each tortilla with the olive oil spray and sprinkle with salt. Place 4 tortillas, un-sprayed side up, on a baking sheet. Spread a lightly heaping 1/4 cup of the lentil puée all over the tortilla, covering it completely.
- Then, spread 1 tablespoon of salsa on each of the tortillas. After that, divide the cilantro and cheese between each tortilla. Cover with the remaining tortillas, so the sprayed side is facing up toward you.
- Gently slide the tortillas under the grill and cook for 3-4 minutes. Gently flip and cook for and additional 3-4 minutes. If some of your topping come out after flipping, just gently press it back in.
- Slice and DEVOUR immediately with extra salsa, guacamole, and sour cream if you choose!
