Heat your grill or grill pan to around 400℉, if you are using a gas grill outside there should be a temperature gauge. If using a grill pan make sure it's smoking.
Oil the grill or grill pan well with spray pan release
Place the burgers on the hot oiled grill surface, don't move them for at least 5 minutes
To make nice grill marks move the burgers ½ turn and leave for another 5 minutes
Flip the burgers and repeat using a probe thermometer check the internal temperature, for chicken it should be at least 165℉
Place the sliced mozzarella on the burgers, place the sliced buns on the grill to toast, or in the toaster or even on the grill pan
Once the burgers have reached the required temperature, and the cheese is melted you are ready to build your burgers!
Combine the mayonnaise and 1 tablespoon of basil pesto in a small mixing bowl
Spread the pesto mayonnaise evenly on both sides of the bun
Place the lettuce and tomato slices on the bottom bun, place the burger on top of them, cap it off with the top of the bun and enjoy!
