Just get yourself a couple of cans of tomato sauce or puree. If you like it chunky, you can also use 1 can diced tomatoes and 1 can of sauce. To make a very basic sauce, just pour the sauces into a bowl. Add salt, pepper, garlic powder to taste, and a teaspoon or so of dried herbs such as oregano or basil. Some people like to add a pinch of sugar as well. Stir this up, and you could heat it if you want it for pasta right away, or use it for pizza sauce.
To get into deeper flavor, saute minced garlic and onion in a tbs of extra virgin olive oil in a sauce pan before adding the tomato sauce and seasonings.
Also, here is my recipe for some fantastic veggie "meat" sauce:
12 oz. package veggie ground round, like Smart Round by Litelife
28 oz. can tomato puree
½ cup dry white wine
3 plump garlic cloves, finely chopped
1 small onion or a large shallot, finely chopped
1 6 oz jar whole button mushrooms, drained and cut in half lengthwise
2 tbs. extra virgin olive oil
½ tsp fennel seed
1 tsp. dried oregano
1 fresh bayleaf, torn but left intact to release flavor
pinch of crushed red chili flakes
1 tsp natural sugar
sea salt and freshly ground black pepper
First, prepare the herbs. Crush the fennel seed and chili flakes with a mortar and pestle, or with the back of a spoon on a cuttin board. Put in a small bowl and set aside.
In a large deep skillet, heat the olive oil on medium-low heat. Add the onions (the oil should lightly sizzle them, not fry and spatter) and cook until soft and translucent, about 3 minutes. Add the garlic and stir for a minute more. Add the fennel and chili flakes and stir to blend with the onion and garlic. Stir in veggie meat and mushrooms until all is mixed. Season with some salt and pepper. Now increase heat to medium high. Pour in the tomato puree (save the can), bay leaf, oregano, sugar, and wine and give it a good stir. Once it starts to bubble, reduce to a simmer, cover the pan and leave it alone for about 20 minutes.
Check the sauce by first observing the consistency. If its too thick, add some water straight from the tomato sauce can, up to a cup or so. Adjust the seasonings by adding more salt and pepper. Stir, cover, and simmer for about 10-15 more minutes, and keep tasting and adjusting seasoning along the way.
