Step 1

Puree the onion in a food processor. Add meat, black pepper, cumin, coriander, oregano, garlic powder, and paprika, and pulse until incorporated, scraping down the sides as needed.

Step 2

Place the meat onto a piece of foil or parchment and form into a log. Tightly wrap it.

Step 3

Transfer the log of meat to the freezer and let it sit for 5 hours or overnight.

Step 4

Remove it from the freezer and carefully slice it into thin strips.

Step 5

Over medium-high, heat some oil or vegan butter in a pan and in batches cook slices in a single layer, on both sides, until browned.

Step 6

Smear sauce of choice on a warmed flatbread, then top with lettuce, tomato, cucumber, and red onion.

Step 7

Add kebab meat and drizzle with sauces of choice, and sumach, if using.

Step 8

Roll up the pita and wrap it with foil to hold it together more easily. Or serve flat on a plate and follow guests or fam to roll it up themselves.
