Combine:

2 lb. hamburger
1 c. bread crumbs (I use 2 bread crusts & cube them in sm. cubes)
1 egg, slightly beaten
1/2 tsp. oregano
1/2 tsp. black pepper
1/8 tsp. garlic powder
1/2 tsp. salt

Brown until hamburger is done (use paper towels to sop up excess grease), then add the following:

2 lg. cans whole tomatoes
2 sm. cans tomato paste
1/4 tsp. oregano
1/2 tsp. red pepper
1/2 tsp. salt
2 tsp. onion flakes or more
2 tsp. green pepper flakes or more
1 tsp. sugar
1 jar mushrooms

Simmer 2 hours. If you want to make the meatballs, make them out of the first 7 ingredients. Brown and let simmer in the sauce.
