Who does not like a mound of mashed potatoes with a big scoop of gravy, if you said, "I don't." then you are unamerican. All that aside, I serve this at Thanksgiving, and no one knows it is a vegetarian gravy. Carnivores can be so easily fooled!
2&1/2 T butter(Vegans use your stuff)
1/4 cup flour
2 cups vegetable broth
2T tamari(Soy Sauce)
1/4 cup chopped parsley(Optional, and I have used dried, but only 1/8 cup)
Melt butter in small saucepan over medium heat. Add flour and whisk together for about 30 seconds, then add broth slowly while whisking. Cook over medium heat for about 2 minutes. Add tamari and pepper to gravy. Whisk until gravy reaches desired consistency.
