Cheesy Hamburger Casserole

Cheesy Hamburger Casserole 1 1/2 lb ground beef 85-15% 1 small onion, yellow, chopped 1/2 large green bell pepper, chopped 2 stalk(s) celery, chopped 1 can(s) diced tomato, 1 lb 12 oz. 1 can(s) diced tomato, 14 oz. 1 tsp salt or to taste 1/4 tsp pepper or to taste 1/2 - 2/3 box of a 1 lb. box of rigatoni pasta cooked according to package instructions. don't forget to add salt to the water. 1 bag(s) cheddar cheese, finely shredded, 2-3 cups Brown meat over meduim heat and then add all chopped veggies and season with salt and pepper. Puree the 1 LB 12 OZ can of diced tomatoes (Whole Peeled Tomatoes can also be used if desired) and add to hamburger mixture. Add the 14 oz. can of diced tomatoes and stir. Cover and simmer until veggies are tender. Taste and add more salt and pepper if necessary. While the sauce is simmering, cook the rigatoni in salted water according to box instructions. Do not overcook the pasta because it will continue to cook when added to the sauce. Drain and add to the hamburger mixture incorporating well. Sprinkle liberally with grated cheddar cheese (I use either mild or medium), cover and simmer until cheese is melted. Hint: I use an electric skillet to prepare this recipe but you can also use a large skillet keeping in mind that it makes a good amount. This is really good for company or to take to a potluck party. Also good for leftovers. Side Dishes are just a green salad and nice crunchy rolls just out of the oven.
