Heat 1 tbsp oil in a large skillet over high; cook burgers with salt/pep 3 min on one side; flip over, cook 2 min, then add 1 slice of cheese to each burger; cover pan + cook 1-2 more min until cooked through + cheese has melted

Cut onion in half from root to stem, peel + thinly slice ½ of the onion

Toast 2 buns until warm + golden; spread 1-2 tbsp garlic sauce onto buns, then add patties + sliced onion—looks great!
