You will not believe how good this tastes after you find out how quick it is! The recipe is from 15-Minute Low-Carb Recipes by Dana Carpender. I used a Vietnamese chili garlic sauce instead of anything called "paste" because my grocery quit carrying the one with the garlic included. I wouldn't go so far as to call the onion "optional," but I left it out because I had none left, so if you are on a strict carb limit or hate onions, you will still love this without it. The book lists 6 g carbs & 1 g fiber (just in case the computer can't tabulate one of the ingredients).
