Preheat grill to high + oil grates; 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 1 tbsp tzatziki then top with burgers; close the lid

Meanwhile, boil a large pot of salted water, add ½ of the orzo + cook 9-11 min or until al dente, then drain + return to pot; wash + slice tomatoes in half then add to orzo; stir in ¼ cup tzatziki + salt/pep; divide orzo salad + burgers to plates, looks good
