Place one tortilla on a plate and spread around 3 Tbsp. of the shredded cheese.
Then lay the thin apple slices on top.
Spread the remaining cheese on top of the apple and top with the other tortilla.
Carefully place the quesadilla in your toaster oven.
I set my oven at 400 degrees and let it cook for about 5-6 minutes.
Carefully remove and cut into triangles.
Enjoy your delicious, hot snack that only took about 10 minutes to make!
