Ground Turkey Tortilla Casserole

I made this for my family and it is a hit for sure. I fixed it and took it to a mommie that just had a baby....they loved it and are asking for the recipe.

6 flour tortillias (Medium)
1 lb ground turkey
1 small onion
1 16 oz can Blackbeans (drained and rinsed)
1(1 1/4 oz) packet taco seasoning
8 oz sour cream
3/4 cup salsa(I use rotel)
2 cups cheddar cheese (shredded)

Directions:

Brown turkey meat and a small onion until meat is completely done
Add taco seasoning packet
Cut(or tear) 3 flour tortillias into bite size pieces and layer them on the bottom of the sprayed casserole dish.
Layer
1 cup cheese
sour cream
black beans
meat mixture
salsa
Cheese
and top with
3 torn tortillias


Bake @ 350 degrees unto cheese is melted and bubbly.
When I remove the dish i sprinkle more cheese lightly over the top and cover so the heat of the dish melts the cheese.

Serve with shreaded head lettue and chips

Optional Ingredients:
Corn
Red or green peppers
