1 Stalk Celery
2 Green Peppers
1-2 cans tomato paste used to thicken up sauce.
Garlic powder (or fresh garlic), oregano and other spices as you desire.
1-2 tea spoons vinegar
2 coups brown sugar
Tomatoes - I love to use fresh tomatoes out of my garden but substitute crushed, whole pealed, or stewed canned tomatoes. To me its the variety of the textures I like. For example I bottle tomatoes and use them year round I will mix with my bottled tomatoes the whole or diced tomatoes from cans (which is thicker in consistency then the bottled tomatoes which are pretty much mush by the time you cook them down.
Cook meat and onions together. I like at this time to also put in garlic and Italian seasonings. Most normal cooks put in a dash of this and dash of that. Don't tell my wife but I put the spices in by the hand full (OK maybe she already knows from buying me all the spices). To me the flavor of the spices is what its all about. Once cooked you can drain some or all of the fat. I give my wife grief for dumping it out but I suppose you can if you like, I leave most mine still in the pot though I do buy leaner ground beef.
Add Celery and Green peppers (diced and chopped) my kids like them in big chunks so they can pick them out. and I dice them really small so they cant.
Cook these tell they are to texture you like them and then add tomatoes/tomato past. Note that My 5 pounds of hamburger is huge I make large batches in 1-2 big pots to freeze left overs. Bring contents to high simmer and then turn down and simmer to cook in. At this time I add in more spices (again by hand fulls) and flavor to taste. I like it STRONG but you may want to maybe put a dash in depending on your taste buds. Also add vinegar and simmer 30 min to an hour depending on the consistency you desire your sauce to be.
Last but most important add the brown sugar. What can I say I love the sweetness of the sugar and the sassy and tarter taste of the tomatoes and the spice of oregano.
Now you can make spaghetti and eat, make home made lasagna or put it in the freezer for later.
