Equipment

  • Skillet use a nonstick skillet or well seasoned cast iron skillet

Ingredients
  

  • 6 each flour tortillas
  • 1 tablespoon olive oil
  • 1 tablespoon fajita seasoning I used Badia Fajita Seasoning
  • ½ ts salt
  • ¼ ts pepper
  • ½ red onion sliced thinly
  • 2 cups sweet multicolored peppers cut widthwise into bite sized pieces; can sub your fave bell peppers cut into your bite sized shape of choice!)
  • 2 cups cheddar shredded (may need a little more or less)

Optional Garnishes

  • guacamole
  • sour cream
  • jalapenos sliced
  • cilantro chopped
  • salsa

Instructions
 

  • Begin by heating up olive oil in a large skillet on medium to medium-high heat. Add the onion, peppers, salt, pepper, and fajita seasoning. Now saute for around 7-10 minutes (stir often) or until the veggies are softened and tender. Taste and adjust for seasoning. Remove this mixture and place on a plate. Take the skillet off the heat and turn down to medium heat if you had it on medium-high heat.
    Sliced red onion, and colored bell peppers with seasonings sprinkled over the vegetables.
  • Assemble your Quesadillas by laying each tortilla down separately. Add shredded cheese (1 cup split into thirds) to 3 separate tortillas. Top each with ⅓ of the veggie mixture to these tortillas. Top with the remainder of the cheese split into thirds so that each tortilla is layered with cheese, veggie mixture, then more cheese. Now top each with remaining tortillas.
    Tortillas placed on a wooden cutting board. 2 of the tortillas are topped with shredded cheese and a sautéed vegetable mixture.
  • Place the skillet back on the stove on medium heat. Pan fry both sides of each quesadilla (flatten a bit with a spatula) for around 1-2 minutes until golden brown and the cheese is melted.

  • To serve your quesadilla, first cut it into wedges. A pizza cutter works very well for this!

Notes

The nutrition information doesn't include nutrition for the fajita seasoning or any optional garnishes that you may choose to enjoy with these quesadillas. 
The cheese you use needs to be shredded. This will help it to melt better and a top tip is to shred it yourself for added meltability!
A pizza cutter is ideal for cutting your quesadilla into wedges. 
These quesadillas are scrumptious served with your favorite salsa, guacamole, and/or sour cream.  Scatter some sliced jalapenos and chopped cilantro over as well!
