Cut tofu into 1/4 inch slices. This makes for very chewy steaks, cut them a little thicker if you'd like them soft. Brush with a thin layer of oil and a dash of steak seasoning.
Heat enough oil to liberally cover the bottom of a large frying pan. Fry tofu on medium high heat until golden brown (~5 minutes) then flip. Brush the tops of the steaks with sauce and fry for another few minutes. Flip, and brush the other side. Fry both sides for a minute or so. The sauce may burn a little, but this adds to the BBQ flavour.
Serve with rice or vegetables, and some extra sauce on top or on the side.
I love this because I don't own a grill, and it really satisfied my craving for barbeque. It's also incredibly quick and easy. I'm sure it would be divine with onions.
