Heat the oil in a 4-quart saucepan over medium-high heat. Add the turkey, onion, chili powder, cumin, oregano, black pepper and garlic powder. Cook until the turkey is well browned, stirring often to separate meat.
Stir the stock, salsa, sugar, beans and corn in the saucepan and heat to a boil. Reduce the heat to low. Cover and cook for 30 minutes or until the mixture is hot and bubbling.
Serve with warm restaurant-style tortilla chips. For dessert serve with sliced watermelon and brownies.
