Broiling the eggplant coaxes out a deeper, more complex flavor. We like to keep the antioxidant-packed skin on, but feel free to peel the eggplant before broiling. You can garnish the dish with extra basil leaves.
Pork shoulder has the double advantage of pairing well with both white and red wines, and being one of the cheaper cuts at the meat counter. Long-braised and roasted, it also delivers a huge amount of flavor. Serve these sandwiches with fresh cilantro sprigs and thinly sliced sweet onions (such as Maui) for each person to add to taste.
