My family's spaghetti sauce recipe:
1lb ground beef. I've used buffalo (better), ground pork or sausage (okay), and turkey (not better) as well.
2 large cans tomato (or puree if you are watching the sodium)
2 cans diced tomatoes (no salt added)
1 can mushrooms
1 can tomato paste
1 large yellow onion
lots of garlic
celery and finely diced bell peppers (optional)
parsley, sage, rosemary, thyme, basic, oregano, bay leaf (as many of these fresh as possible)
little bit of chilli pepper
salt to taste
Brown the meat, adding olive oil if needed due to lean meat.
When the meat is almost browned add in the onion (diced) and the garlic until the onions are cooked.
Drain the fat (if there is any to drain).
Dump everything in the crock pot for many hours.
Server over standard spaghetti noodles and a side of pesto
