I prefer to make sauce at home rather than buy cans or jars, as I find they have too much salt and way too much sugar in them.
What you need: 1 large can of crushed tomatoes; 1 large can of diced tomatoes;1 can of water; 500 - 600 grams of lean ground beef, 1 small onion, 3 - 4 cloves of garlic, 1/4 cup thinly sliced celery; your favourite blend of Italian spices, or some thyme, cilantro or parsley, basil, and oregano; chilli powder or sambal oelek for a little heat; a little flour (or corn starch, if gluten free) to thicken sauce. Salt and pepper to taste. Optional, 1/4 cup chopped green peppers, or a small can of spicy pepper mix tomatoes. As an alternative, you could add a cup of your favourite salsa to the sauce.
What you do: Brown the meat, with onions, garlic and celery, on medium high heat, in a large saute pan or Dutch oven until well done. Add salt and pepper. Drain off extra fat. Add tomatoes. Fill one can with the water, and blend the flour or corn starch into it. Add to pot. Stir over medium heat until mixture thickens. Add your spices or herbs, reduce heat to lowest, and let simmer for at least 40 minutes, to allow all the flavours to meld.
Serve over your favourite pasta, like spaghetti, bow ties, etc. along with a green salad and garlic bread.
As always, enjoy.
