Dinner Tonight: Lamb Burgers With Red Onion Relish Recipe

• 1 tablespoon olive oil
• 1 large red onion, thinly sliced
• 1 tablespoon red wine vinegar
• 1 tablespoon minced fresh rosemary
• 1 1/2 teaspoons sugar
• 1 1/2 tablespoons mustard
• 1/4 cup yogurt
• 1 tablespoon lemon juice
• 1 1/2 pounds ground lamb
• 2 cloves garlic, minced
• 4 pita pocket halves
• 1 cup spring greens
• Salt and pepper to taste

1. In a large (12-inch) skillet, heat the olive oil over medium heat until shimmering. Add the onion and cook, stirring often, until soft and caramelized, adding water to the pan if necessary to prevent burning. Add the vinegar, rosemary, sugar, and 1 tablespoon of mustard and continue cooking for a few more minutes to blend the flavors. Season to taste with salt and pepper.
2. Crumble the ground lamb loosely into a bowl. Add the garlic, 3/4 teaspoon salt, and 1/4 teaspoon pepper. Gently work the garlic and seasoning into the meat, taking care not to overwork the meat so they burgers are not tough. Gently hand-form the meat into 4 patties.
3. Prepare a grill or preheat a grill pan over high. Brush the grates or grill pan with olive oil to prevent sticking, then grill the burgers to desired temperature. Remove from the grill and allow to rest for a few moments.
4. Brush the pita pockets with a little olive oil and grill briefly until soft. Combine the yogurt, lemon juice, and remaining mustard and toss with the greens.
5. To construct the burgers, stuff the pitas with dressed greens, then burgers and onion relish. Serve immediately.
