Heat a large nonstick skillet to medium heat and add a tablespoon of cooking oil
When the skillet is hot, and the diced red pepper and onion, chopped kale and chili powder then saute for a couple of minutes until the veggies have just softened.
Remove the veggies from the skillet and wipe clean with a paper towel, then place it back on the burner.
Spread out ¼ of the cheese across one half of a tortilla. Top with half the veggies and half the black beans then spread another ¼ of the cheese on top of it all.
Fold over the empty half of the tortilla and press gently to close the quesadilla.
Repeat for the second quesadilla
Place both the quesadillas in the skillet and cook for 3-4 minutes per side or until the cheese has melted and the exterior of the quesadillas has crisped and browned.
