Finely chop the onions.
Peel the tomatoes, then finely chop them using a serrated knife. See the note below for instructions on how to peel the tomatoes.
Over medium heat, add the oil to a pot. Add the chopped onions and sauté until tender.
Add the chopped tomatoes and cook for 5 minutes, until they release their juices. Then add the water.
Stir in the coarse bulgur and tomato paste. Season with salt and crushed red pepper. Stir well.
Cover the pot and cook over low heat for 30 minutes. Serve with pita bread, sliced onions, and radishes.
Alternatively, make wraps with bulgur-tomato pilaf using Lebanese or pita bread. Add some tomato wedges, onion slices, pickles, and a small drizzle of pomegranate molasses. This makes an excellent weeknight dinner, especially for vegetarians.
