Lamb Burgers with Feta-Yogurt Spread
These showstopping lamb burgers have salty and briny capers studded throughout them, and get some earthy notes from cumin. The accompanying feta-yogurt spread is the perfect match: It's creamy and salty, but also has freshness from mint and a hint of warmth from ground nutmeg. Spreading it on both the top and bottom brioche buns envelopes the burgers from both sides and helps hold the burger, red onion, arugula, and cucumber together. If you'd like, serve the burgers with sweet potato fries to round out the meal.
