3Mix the meat — In a large bowl, combine the beef, lamb, grated onion, garlic, yogurt, and all of the spices. Mix for 3-4 minutes until the mixture becomes smooth and paste-like.
4Shape the portions — Divide the mixture into 4 equal portions. Roll each portion flat between two sheets of parchment paper, then shape into a log.
5Bake the meat — Place on a sheet pan and bake for 15-18 minutes, or until fully cooked.
6Salad and Tzatziki
7Mix the sides — While the meat cooks, prepare the salad and tzatziki by mixing all of the ingredients together in separate bowls.
8Finishing
9Slice and broil — Let the meat rest for a few minutes, then slice it thinly. Return it to the sheet pan and broil for 3-5 minutes until the edges are browned and slightly crispy.
10Serve the kebab — Serve in warm pita or naan with the salad, tzatziki, and feta if desired.
