Preheat oven to 350°.
Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Add onion, bell pepper, chili powder, cumin, and garlic to pan; sauté 1 1/2 minutes or until onion is tender. Stir in chipotle chile; sauté 30 seconds. Remove from pan; cool. Combine onion mixture, turkey, turkey breast, breadcrumbs, 1/3 cup salsa, oregano, bacon, and egg whites in a large bowl.
Place half of turkey mixture in an 8 x 4-inch loaf pan coated with cooking spray. Arrange cheese over top, leaving a 1/2-inch border around outside edges. Arrange remaining turkey mixture over cheese, pressing edges to pack. Spread the remaining 1/3 cup salsa over top of meat loaf. Bake at 350° for 1 hour and 25 minutes or until a thermometer registers 165°. Let stand 10 minutes. Remove from pan; cut into 12 slices.
