1. Thaw out the tofu. Slice each pound block into three thick slices. Place the slices on a cookie sheet covered with a couple of clean, folded tea towels. Cover the slices with more tea towels and another cookie sheet. Weigh this arrangement down with something heavy for about 15-20 minutes. Now the tofu slices are ready for marinating.
2. Mix the marinade ingredients together and pour over the prepared tofu slices in a shallow container in one layer. Cover and let marinate for several hours or days.
3. Just before serving, pan-fry on a lightly-oiled heavy skillet or nonstick skillet over medium-high heat until browned on both sides. Or cook on an indoor grill. Serve on buns with all the trimmings.
