Prepare pasta/rice/etc.
Melt the "cheese" in a saucepan over medium - medium-high heat, adding water/soymilk/other liquid to thin to the sauce to the consistency that you'd like to eat over your pasta/rice/etc.
Stir in vegan burger-style crumbles (equal amount to the sauce, or whatever amount pleases you) and heat until warm enough to eat.
Season with salt, pepper, and other seasonings of your choice to taste.
This recipe was a complete accident--I was planning to melt some of the "Vegan Gourmet" "Jack" cheese and mix it with some vegan burger-style crumbles to use over tortilla chips or such (i.e., Mexican-style), but as the sauce was cooking, I realized it smelled *exactly* like the beef stroganoff my mom used to make when I was a kid. I tasted the sauce and was further bowled over by the similarity. I plan to add some sauteed mushrooms next time. The best thing about this recipe is how incredibly easy it is.
