In a large skillet over medium heat, add the ground beef. Break it apart with a spatula and cook until browned, about 5-7 minutes.

Once the beef is browned, sprinkle in the taco seasoning.

While the beef cooks, lay out the tortillas on a clean surface.

On half of each tortilla, layer the cooked beef, cheese, and optional veggies. Fold the tortilla in half to enclose the filling.

In the same skillet, add a little cooking oil over medium heat.

Place the folded quesadilla in the skillet and cook for 3-4 minutes on each side.

Once golden brown and crispy, remove from the skillet and let cool for a minute. Slice into wedges for easy serving.

Serve with sour cream and salsa on the side.
