You don’t grill the lettuce at all nor do you put it in the pan. You pour the dressing over a bowl of cold lettuce. You add the bacon back in after the dressing has boiled. I’ve never heated any back up as it is suppose to be over cold lettuce. So you could portion out the amount of lettuce you want , use as much dressing as you want and then reheat the dressing for another time.

I don’t know if I would like reheated lettuce...think it is soggy by now.
