1 stalk celery chopped
2 cloves garlic minced
1 C uncooked instant rice
1-28 1/2 oz can diced tomatoes undrained

Break up hamburger in an electric frying pan or a deep skillet over medium heat, stirring until hamburger is browned. Drain fat and return hamburger to pan. Add remaining ingredients except zucchini. Cover skillet tightly and cook on low heat for about 20 minutes. Stir in zucchini, replace cover and cook until liquid is completely absorbed into the rice. Sprinkle cheddar and mozzarella cheeses over the top and cover until the cheese has melted. Garnish with corn chips around the edge and serve right from the skillet.
