Preheat oven to 350°.
Spray 9x13 baking dish and set aside.
Prepare apples and vegetables.
Spray medium pan with olive oil spray and warm over medium heat.
Add diced onion and cook until translucent - approx 2-3 mins.
Add diced Envy apple and jalapeno.
Saute until peppers start to soften, approx 2-3 mins.
Add in cooked chicken and mix well and mixture is heated throughout.
Lay out 8 tortillas on the kitchen counter. I like to lay them all out at once, it just seems easier!
Sprinkle a little cheese near one side of each tortilla.
Add the chicken and apple mixture to the same side as the cheese of each tortilla.
Using your hands, tightly roll each tortilla and place it seam side down into the prepared baking dish.
Top with the red enchilada sauce.
Bake for 15 - 20 mins until they are heated throughout.
Top with remaining cheese and place back into the oven until cheese is melted.
When ready to serve, top with cilantro and additional jalapeno slices if desired.
