Cover bulghur wheat with cold water by 1 inch above the grain. Soak for 30 minutes. When plump and tender, drain the grains, squeezing out as much water as you can with your hands. Set the grains in a double layer of cheesecloth and squeeze out even more water.
Combine the bulghur wheat with chick peas, parsley, mint and scallions and tomatoes. In a small bowl combine lemon zest with olive oil and juice; season well with salt and pepper and stir into salad. Add more olive oil or lemon juice and serve immediately.
