Instructions

  1. For caramelized onions, peel red onions and slice into 1/2-inch (2 cm) rounds.
  2. Combine balsamic vinegar, soy sauce (if using), olive oil, salt and pepper in a large bowl.
  3. Add onions to bowl, and gently toss to coat. Marinate one hour.
  4. Remove onions from bowl, reserving marinade. Place onions in a lightly oiled grill basket, or directly onto the grill.
  5. Cook for 4 to 6 minutes per side, brushing with reserved marinade until onions are soft and begin falling apart.
  6. For burgers, gently combine all ingredients in a large bowl. Form into 4 to 6 patties of equal size.
  7. Lightly oil grill and set barbecue to high heat. Cook burgers for 4 to 6 minutes per side, or until a meat thermometer inserted into the middle of the burger reaches at least 160°F.
  8. Remove from grill, top with caramelized balsamic red onions and serve with your favourite gluten-free bun and condiments.
