Gluten free Cheeseburgers with Onion and Zucchini

• Peel and finely chop the garlic, then mix it into the ground beef along with a generous pinch of salt. Combine thoroughly in a mixing bowl, then form the mixture into 4 evenly sized burger patties.
• Peel the onions and slice them into rings. Trim the ends off the zucchini and slice them thinly.
• Preheat a ridged cast-iron grill pan. Slice the hamburger buns in half and toast the cut sides on the hot grill until lightly golden.
• Grill the zucchini slices briefly on each side. Once grilled, drizzle them with a little olive oil and season with salt and chopped parsley.
• Cook the burger patties on the grill pan, flipping them after about 2 minutes, or once nicely seared.
• To assemble the burgers:
  • Start with lettuce and onion on the bottom half of each bun.
  • Add the burger patty, followed by a slice of tomato and the grilled zucchini.
  • Top with a slice of cheddar cheese and the top half of the bun.
• Serve hot and enjoy!

Chef’s Tip: For a richer, more robust flavor, try using 2 cups of ground beef and 1 cup of ground lamb in the patty mix.
