This is easy and tasty! I broiled my tomatoes and they were perfect in 10 minutes...the skin came right off. I only used 3 tomatoes and half the olive oil. I used a red onion. I substituted mustard seeds for the nigella seeds. I garnished it with fresh cilantro. This could be a quick meal if you put on some rice. Put the tomatoes under the broiler and start cooking the onions all in a row. My husband really LOVED this! Made for Zaar Tag.
