Heat a pan, grill the zucchini and keep aside. In a pan, cook the slices of tofu in a mixture of the soy sauce and water and keep aside. Take a slice of the potato and place the zucchini, tofu slices, tomato sauce, salt, pepper and basil leaves on it. Cover with another slice of potato so that it resembles a potato sandwich. Hold together with a tooth pick and tie the bundle with spring onion greens so that it looks like a wrapped potato sandwich.
Serves 2 – 3
