Lamb-Mushroom Kabobs with Greek Yogurt Mopping Sauce

Mix olive oil, red wine, parsley, Dijon mustard, minced garlic, mint, pepper, and kosher salt for the marinade together in a bowl. Coat leg of lamb cubes and mushrooms in separate bowls; marinate for 24 hours.

Whisk Greek yogurt, egg, wine, oil, lemon zest and juice, smoked paprika, mushroom powder, red pepper flakes, garlic, oregano, saffron, salt, and pepper for mopping sauce together heavily so everything mixes together. Refrigerate for a minimum of 6 hours, to overnight.

Place a piece of lamb leg, red onion, cremini mushroom, merguez sausage, and another piece of red onion on 7 grill-safe skewers. Repeat with ingredients for as long as your skewer is able to handle and rotate evenly.

Preheat an outdoor grill for high heat and lightly oil the grate.

Place kabobs on the preheated grill to sear in juices and form a crust on lamb, rotating occasionally, 4 to 5 minutes.

Reduce grill temperature to medium-high. Coat kabobs with a generous layer of mopping sauce. Let brown and bubble and continue to coat until an instant-read thermometer inserted into a piece of sausage reads at least 142 degrees F (61 degrees C). The leg of lamb should come to 125 degrees F (52 degrees C) for medium-rare.
