I feel strongly that lettuce should be used for more than just salad: don’t be afraid to cook it. Smoky bacon is obviously delicious, but the cooked, wilted lettuce is what shines in this dish. I much prefer skin-on slab bacon, but I know it can be hard to find. Ideally you can get your hands on a whole piece of pork belly so you can cut large pieces, but sliced bacon will work in a pinch (in which case, there’s no need to boil it, just cook it with the olive oil until crispy).
