First, use a sharp knife to slice the head of lettuce in half from top to bottom. Then rinse and dry the lettuce. It is important to let the lettuce dry because any water on the lettuce when it is placed on the grill will steam the lettuce causing more wilting, and the edges of the lettuce will take longer to char.

Place the lettuce on a grill over medium heat, inside of the lettuce facing down. Check on the lettuce after a minute. You want the edges of the lettuce to be slightly charred. Grill for longer if necessary.

Remove the lettuce from the grill and place on a serving dish. Top with the Parmesan and Caesar dressing. Serve immediately.
