Combine the bouillon granules, cornstarch, sugar, onion, garlic, parsley, ginger and red pepper in a jar or other airtight container. Store up to 1 month in a cool place. To use, combine 1 tablespoon of the mixture with 1/4 cup liquid (water, broth, etc) and let stand for 3-5 minutes. Add to stir-fried vegetables or meats and cook, stirring constantly over medium-high heat until the sauce thickens.
