Prepare tofu by draining all of the liquid. Press the tofu (see post for detailed instructions) and grate on a box grater.
Using a small amount of oil in a skillet over medium high heat, brown the tofu, stirring infrequently.
When the tofu is browned, add the remaining ingredients and cook until thickened.
Serve on a standard hamburger bun with a side of chips and pickles :)
