I don't do anything fancy. Ha. But since you asked... It depends on what I have on hand. For a basic sauce, the base is tomato sauce (unsalted, because that way you can add how much salt you want instead of someone else deciding for you)… then I add the seasonings / dried herbs (like oregano and other herbs) then I add maybe half an onion, salt, pepper, garlic powder…. and I let it simmer. Then separately whatever meat substitutes I have, like ground “beef”... I brown that in a pan, or sometimes I use Gardein meatballs… and then I just add the “meat” to the simmering sauce. That’s about it. And not to get on this topic (don't worry) but I bet if you had it, you wouldn't even be able to tell that it was vegan.
