Heat oven to 400°F.

Spray a skillet with nonstick cooking spray. Preheat skillet over medium-high heat.

Add ground turkey to hot skillet. Stir to crumble, approximately 14 to 16 minutes. Always cook to well-done, 165°F. as measured by a meat thermometer.

Add onion, green pepper, tomatoes, corn, olives and salsa. Bring to boil, stirring occasionally. Cover and simmer 15 to 20 minutes. Meanwhile, prepare cornbread muffin mix as specified on package. Spread batter into greased deep dish pizza pan. Bake 8 to 10 minutes or until lightly browned.

Remove cornbread from oven, sprinkle with 1 cup cheese. Spread turkey mixture on top of cheese, then top turkey mixture with remaining 1 cup of cheese.

Bake 4 to 5 minutes or until cheese is melted.

Serve with shredded lettuce, sour cream and taco sauce, if desired.
