Grilled Halloumi Burgers with Citrus Tapenade
These vegetarian burgers feature halloumi, a tangy, salty cheese from Cyprus that holds its shape when heated, making it ideal for the grill. When grilled or sautéed, halloumi develops a charred crust that yields to soft cheese inside. Here, we cut the halloumi across the equator for the centerpiece of the burger, and season it with cumin, salt, and pepper. It's then topped with a citrusy olive tapenade with just enough crushed red pepper flakes to lend it a touch of heat. A lemony aïoli complements the citrus in the tapenade and natural tang of the halloumi. The roasted red peppers round out this burger; be sure to blot them dry before using so they don't slip out of the bun when you take a bite. Try to seek out brioche buns for these burgers; their slightly sweet flavor works perfectly here.
