Pour a healthy amount of olive oil into a pan - enough to cover it and then a dollop more - and heat up. Saute the garlic and onions until translucent. Next add in the mushrooms and cook until the aroma starts come out.
Pour the tomatoes and the tomato paste in and bring to a boil. Once at a low boil add in the white wine, herbs, seasonings, bouillon, and sugar. Simmer at least a half hour adjusting for taste.
