How do you make vegan gravy?

Melt some vegan margarine in a pot, and then turn off the burner & add enough flour/cornstarch/arrowroot/whatever to make a thick paste. (This is called a roux.) Then add some broth (or boullion disolved in hot water), mix it up well with the roux so there's no lumps. Turn the heat back on medium/low & just let it simmer for a bit while almost constantly stirring, so it doesn't burn on the bottom. Keep cooking 'til it's thick enough. I also like to add some Bragg's/soy sauce and/or miso paste. Ocionally, I'll also add some sauteed onions or finely chopped mushrooms, depending on how ambitious I'm feeling. :) If you don't add Bragg's, you probably would want to add a little salt and/or other herbs. Sage or "poultry seasoning" (It's vegan.) are great for gravy.
