In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced bell pepper and zucchini, sautéing for approximately 5 minutes until they begin to soften and become fragrant.
Stir in the drained black beans, corn kernels, and chopped spinach. Sprinkle in the ground cumin, smoked paprika, and season with salt and pepper. Cook the mixture for an additional 3-4 minutes, allowing the spinach to wilt and all the flavors to meld together. Once done, remove the skillet from heat and let the filling cool slightly.
In the same skillet, add the remaining tablespoon of olive oil and heat over medium heat. Place one tortilla in the skillet. On one half of the tortilla, layer ¼ cup of shredded cheese, followed by a generous scoop of the veggie mixture, and then add another ¼ cup of cheese on top. Carefully fold the tortilla in half to encase the filling.
Allow the quesadilla to cook for 3-4 minutes on one side, or until it's golden brown and crispy. Carefully flip the quesadilla and cook the other side for another 3-4 minutes until it's equally golden. Repeat this process with the remaining tortillas and filling.
Once the quesadillas are crispy and golden on both sides, remove them from the skillet and cut into wedges. Serve warm, garnished with fresh cilantro and lime wedges on the side for an extra zesty kick.
Notes
Serve with fresh cilantro and lime wedges for added flavor.
