I take wheat crackers (I use Vita-Wheats, but I don’t know what the US equivalent is), spread the crackers with tahini, sprinkle them with a bit of grated carrot, and then place half a slice of fresh tomato on each one. Then I fry slices of firm tofu in olive oil, and place one slice on top of each cracker (on top ot the tomato) while still hot. It’s one of my favourite foods… and really filling.
