Form the kofta into patties and grill them over charcoal. For the onion mix: thinly slice the onions as needed and mix with coarsely chopped cilantro as needed. Mix salt and sumac with the onion and cilantro.

Spread the spicy red pepper on a piece of bread with a sprinkle of the onion mix, heat over charcoal, and serve the kofta hot with hummus dip, the onion mix, and tomatoes.
