I think just about every person out there has their own way of making spaghetti sauce. This is mine:
1 lb ground beef or italian sausage
1 small onion
3 cloves garlic
1-2 tsp fennel seeds
1 med can tomato sauce
1 med can diced tomatoes, don't drain
2-3 TB italian seasoning
1-2 tsp onion powder
1-2 tsp garlic powder
1-2 TB red wine vinegar
1-2 tsp tabasco, or red pepper flakes
salt and pepper to taste
fresh basil and parsely if available
Over med heat saute beef, garlic and onion until beef is brown and onions are soft. Add remaining ingredients to desired taste. Simmer for about fifteen minutes until sauce is desired consistency. Enjoy!
