If you still want eggs in your sandwich, it's simple to adapt this fried tofu bánh mì omelet recipe to work with English muffins, biscuits, or bagels -- or sub in the aforementioned tofu bacon ...

Cut the firm tofu in half, then into 2cm thick slices ... Gently lift up the folded omelet and add the raw egg to run under it. Cover with more nori, then turn it over. Repeat this process ...

When hot, add the tofu cubes. Cook, tossing every few minutes ... as though you were making a very thin omelet. Pull the cooked edges in, then tilt again, to let the uncooked egg hit the pan.
