Crisp, warm tortillas stuffed with chicken, peppers, and plenty of melty cheese make a great dinner or a great way to use up some leftovers. Who would turn down a piping hot chicken fajita quesadilla for lunch? (Not me!)

Fajita Quesadilla
My sister taught me how to make absolutely delicious quesadillas many years ago, and they’ve been a staple at our house for breakfast, lunch, and dinner ever since.
Experimenting with quesadilla fillings is endless fun and we’re really loving these fajita quesadillas lately. Grilled peppers or roasted peppers and onions go great with quesadillas.

Add some beef, chicken, pork, or shrimp and you’ve got a fajita quesadilla that will dwarf anything you can order at a restaurant.
What are fajitas?
Fajitas are a Tex-Mex dish that is typically thinly sliced ​​grilled meat served with peppers and onions on a tortilla. While traditionally everything is grilled, there are countless ways to combine meat and veggies for a quick and easy fajita dinner at home.
We are longtime fajitas fans and have been making these chicken fajitas for over 12 years. (And yes, it badly needs new photos.)
Beef strips, peppers and onions are slow cooked with Mexican spices and a generous drizzle of lime to create these slow cooker steak fajitas. This is one of the easiest crock pot dishes we’ll make.
I call these slow cooker chicken fajitas a “quick crockpot meal,” meaning you can start them in the afternoon when you have a spare minute and have them ready by the evening when everyone is hungry.

Fajita Quesadilla Recipe
Preheat a large non-stick skillet to medium-high heat. Lightly butter one side of each tortilla with about 1/2 teaspoon butter and place one side, tortilla butter side down, in the hot skillet.
Sprinkle about â…“ cup cheese over the tortilla and top with cooked chicken, peppers, and onions. Place the remaining tortilla on top, buttered side up, and cook for 2-3 minutes.
When the cheese begins to melt and the bottom tortilla is lightly browned, flip the quesadilla to cook the other side. Continue cooking until all the cheese is melted and the tortilla is crispy on the edges.

Serve the quesadillas with chipotle lime rice, hot Mexican corn dip, or street corn coleslaw for a dinner everyone will enjoy.
