1. Heat oven to 350 degree F. Heat oil in medium nonstick skillet over medium heat. Add onion and bell pepper; cook, stirring occasionally, until tender, 5 to 10 minutes. Stir in chili powder, cumin, garlic, and red pepper; cook 30 seconds more. Transfer to large bowl and cool.
2. Add beef, bread crumbs, corn, 1/3 cup ketchup, and the milk, egg and egg white, salt, and black pepper; mix well. Pat into 9x5-inch loaf pan. Spread remaining 2 tablespoons ketchup on top. Bake 75 to 80 minutes until an instant-read thermometer inserted in center of loaf registers 160 degrees F for beef; 165 degrees F for turkey or chicken. Let stand 10 minutes. Discard any drippings. Unmold and slice. Makes 8 servings.
