Instructions
Cook time: 13 minutes
Preheat grill to high + oil grates; cut off the stem of 1 onion, discard outer skin, then carefully slice onion into ¼ to ½-inch rounds; drizzle with oil + salt/pep; grill 5 min with lid closed, flip + grill 4-6 min until charred + slightly softened
Meanwhile, form lamb into 2 patties, rub with 1 tbsp oil + salt/pep; grill 5-7 min with lid closed, flipping over halfway through cooking
Grill 2 buns until warm + golden; spread each bun with 2 tbsp tzatziki then top with burgers + grilled onions; close the lid—looks good!
