Chicken and mango quesadilla pie

I've made Quesadilla Chicken Pie several times since I first started experimenting with it, and my most recent rendition involved mango salsa and feta cheese!

Quesadilla Mango and Chicken Pie

Extra large flour tortilla
Cooking spray

Vegetable oil
2 chicken breasts, chopped 
Large handful of arugula

1/2 c mango salsa plus more for serving
1 c crumbled feta cheese
1/2 c flour
1/2 t baking powder 
1/2 c milk
1 egg

Spray 10 inch deep dish pie pan and press tortilla into it.  Lightly spray the tortilla. 

Saute chicken until cooked thoroughly.  Add arugula and wilt.  Remove skillet from heat.

Spread mango salsa onto tortilla.  Top with the chicken mixture and add about 3/4 c of the cheese.  In a small bowl, mix the flour through the egg well and pour over the tortilla.  Top with the remaining cheese.  Cook at 450 for about 20 minutes.  Serve with more salsa.
