Ingredients ¼ cup (½ stick) unsalted butter 3 tablespoons chopped fresh parsley 3 pounds mussels, rinsed and scrubbed 2 lemons Coarse salt and ground pepper Directions Heat a grill or grill pan to medium-high. Clean and lightly oil hot grill. In a small pot, melt butter over medium. Remove from heat and stir in parsley; set aside. Working in batches if necessary, place mussels on grill in a single layer. Place lemons, halved and lightly oiled, on grill, cut side down. Grill until mussels open and lemons are warmed through and browned, 5 minutes.
