  • 1 small cucumber, seeded and cut into fine dice (about 1 1/2 cups)
  • 1 large ripe tomato, seeded and cut into fine dice (about 1 cup)
  • Kosher salt
  • 1 tablespoon lemon juice
  • Freshly ground black pepper
  • 1/2 cup Greek-style yogurt
  • 1/4 cup mayonnaise
  • 1/2 cup finely crumbled feta cheese
  • 1 medium clove garlic, minced (about 1 teaspoon)
  • 20 ounces freshly ground beef, divided into four 5-ounce patties
  • Sliced white or sweet onion (such as Vidalia)
  • 4 toasted hamburger buns


  1. 1.

    Combine cucumber and tomato in a colander or fine mesh strainer set in the sink or a bowl. Season with 1/2 teaspoon salt and toss to combine. Let drain at least 15 minutes. Discard liquid and transfer to a small bowl. Toss with 1 teaspoon lemon juice and season with pepper. Set aside.

  2. 2.

    While tomatoes drain, combine yogurt, mayonnaise, feta, garlic, remaining 2 teaspoons lemon juice, and 1 teaspoon black pepper. Season to taste with salt.

  3. 3.

    When ready to serve, season burger patties generously with salt and pepper and cook burgers to desired doneness on a hot grill or in a skillet on the stovetop, 125°F for medium rare or 135°F for medium.

  4. 4.

    Place onion slices on bottom bun. Top with burger patty. Top with sauce and cucumber/tomato relish. Close burgers and serve immediately.
