Lamb kebabs in onion marinade

Ingredients:

• 700 g lamb fillet, trimmed and cut into 5 cm cubes (about 30 pieces)
• 1 large onion, cut into 4 pieces
• 1.5 tsp dried oregano
• 1 tsp ground cumin
• Vegetable oil, for frying
• Salt flakes, for sprinkling
• Tzatziki sauce, for serving

Preparation:

1. Puree the onion in a food processor until smooth. Strain through a fine-mesh sieve over a medium bowl. Stir in the onion juice, oregano, cumin, and 1/2 teaspoon each of coarse salt and freshly ground black pepper. Add the lamb and stir. Cover and refrigerate for at least 1 hour or overnight.
2. Preheat the grill to medium-high heat and brush the grates with vegetable oil. Remove the lamb from the marinade and thread the pieces onto 4 metal skewers. Grill, turning occasionally, for about 8 minutes for medium-rare. Sprinkle with flaky salt and serve the lamb kebabs with tzatziki sauce.
