How to Make It
Heat the oil in a large skillet over medium-high heat. Add the onion and celery; saute 5 minutes or until tender and lightly browned. Add basil and the next 5 ingredients (basil through garlic); cook 2 minutes. Remove from heat; stir in vinegar. Combine onion mixture, meat, breadcrumbs, 1/2 cup corn, and parsley in a large bowl; set aside.
Place the remaining corn and egg in a food processor, and process until almost smooth. Add to meat mixture; stir well (mixture will be wet).
Shape meat mixture into a 9 x 4-inch loaf. Place meat loaf on a broiler pan coated with cooking spray. Bake at 350° for 30 minutes. Brush tomato sauce over meat loaf; bake an additional 35 minutes. Let stand 5 minutes before slicing.
