Eri's Delicious Pasta Sauce

I've never tried to write down a recipe for this. I always just make it! So the amounts will be innacurate somewhat. More or less according to your own tastes, but everyone says that no matter how I make it, it's delicious. It also makes a very large batch, and is perfect for freezing and using later.

1 each: stoplight peppers (red, green and yellow, I also use orange)
1 head of garlic
1 sweet yellow onion
Olive oil, extra virgin has a nice light taste.
1 bunch fresh basil, chopped fine (not the whole bunch, use your judgement)
1 bunch fresh oregano, chopped fine (see above statement)
1 bunch italian parsley, chopped fine (see above statement)
up to 6 12oz? cans diced ORGANIC tomatoes. (I've had people say that it doesn't make a difference, but I can tell)
2 12oz cans ORGANIC tomato sauce
1 small can tomato paste. I sometimes have trouble finding this organic, but you can find it.
One 16oz package frozen MorningStar Farms soy-sausage crumbles. If you can't find this, the sausage patties work well too, just crumble them up.
If you have one of those amazing huge spice racks, you will use the marjoram, thyme, rosemary and sage. If you don't have one of those, use "Italian Seasoning"

Chop the peppers, onion and garlic, put in a pot with the olive oil. I use enough oil so everything is lightly coated. When the onions are starting to get clear, add the fresh herbs. Let them "sweat" for a minute or two, then add the cans of diced tomatoes. Reduce the heat, let simmer for a while. Add the tomato sauce, one can at a time. Sometimes only one can is needed. Add the soy-sausage, stir well to make sure the goodness is all over. Not, you know, outside of the pot though, because you don't want the kitchen to be a mess. Keep tasting the sauce, adding the marjoram, thyme, rosemary and sage if you feel it is needed.

The best I ever made this sauce I had let it simmer on the lowest setting on the stove for about three hours. I had forgotten that it was there and went to the store! When I came back it was the best the house had ever smelled. Just amazing!
