Iranian / Persian Salad Shirazi
An excellent light side salad to accompany a heavy Persian meal or any meal really. Sumac is the red bitter spice usually served for sprinkling on kebab. It's available at most Middle Eastern stores, but if you can't find it just leave it out. I like to dice the veggies very small about 1/4-inch. Serve with fresh lemon wedges.
To remove seeds from the tomatoes, slice them in half and squeeze.
