Lamb & Mint Burger with Feta and Balsamic Onions

Serves 4

INGREDIENTS

4 Lamb & Mint Burgers
2 tbsp. extra-virgin olive oil

1½ tsp. high-quality balsamic vinegar
1 small red onion, halved and thinly sliced (1 cup)
Baby greens (optional)
4 Brioche hamburger buns, halved and toasted
½ cup crumbled Feta 

METHOD

1. Heat a large, cast-iron skillet or outdoor grill over medium-high heat. When the surface is smoking hot, add the patties and cook for 3–4 minutes per side or until preferred doneness. Transfer the patties to a large plate, and set aside to rest for 5 minutes.
2. In a medium bowl, toss the olive oil and the vinegar, onions, and greens (if using).
3. Transfer the burger patties to the brioche bun bottoms, then divide the onion mixture and feta among the patties. Top with the remaining halves of the buns, and serve immediately
