Grilled Beef-Mushroom Burgers
Blending finely chopped mushrooms with ground beef adds great flavor, moisture, and even fiber to these no-bun burgers. Garlicky cucumber-yogurt sauce is tasty Middle Eastern–inspired alternative to standard ketchup and mustard. Served with a juicy slice of fresh tomato and crisp butter lettuce, these burgers are naturally gluten-free. Double the greens and tomato and call it a burger salad. If you're in the mood for bun, try these tucked into warm whole-wheat pitas instead.
