Slice the tofu into 1/4 inch slices.
Put the tofu on a plate or in a shallow bowl and cover with the barbecue sauce. Let it marinade for 5-10 minutes.
Warm the oil in a pan over medium heat. Add the marinated tofu and a little extra sauce. Cover and cook until it is warm.
Serve on a whole grain hamburger bun with all of the fixings.
This sandwich goes well with a green salad.
Use the barbecue grill: Cut the tofu into slightly thicker slices, marinate and cook on the grill!
