In a large oven-proof skillet heat the olive oil over medium-high heat. Add the diced onion and bell pepper and cook until softened, about 5 minutes. Add the garlic and cook for 30 seconds. Add the ground turkey, chili powder, salt, and pepper, and cook, stirring, until the turkey is cooked through – about 5 minutes. Add the tomatoes, beans, taco sauce, and steak sauce and simmer for 15 minutes or until heated through.

Preheat oven to 375 degrees.

Cut the polenta in half lengthwise then cut into ½-inch half circles. Layer the polenta over the top of the chili, sprinkle with the cheese and cook for 30 – 40 minutes or until the cheese is melted and golden brown.

Top with cilantro if desired and serve
