Preheat oven to 350. Spray an 8x12 or 9x13 baking dish with non-stick spray and set aside.
In a large skillet, add 1 tablespoon of the melted butter. Over medium high heat, cook the bell pepper and onion until tender. Add the ground turkey and cook until browned and no longer pink. Remove from heat, drain, and return to the skillet. Stir in half of the salt, all of the chili powder and garlic powder.
Spoon the turkey mixture into the bottom of the prepared baking dish.
In a large bowl, whisk the eggs until they are light and fluffy. Quickly whisk in the flour, baking powder, black pepper and remaining salt.
Add the cottage cheese, cheddar cheese, remaining butter, diced tomatoes and black olives to the egg mixture. Stir to combine.
Pour the egg and cheese mixture on top of the browned turkey. Stir in the baking dish to combine.
Bake uncovered for 45 minutes or until the center is set. (Baking times will vary based on size of pan and oven.)
Let rest for 15 minutes before serving. Cut into squares or serve with warm flour tortillas and salsa.
