Fettuccine with Mussels, Chorizo, and Lemon Butter

Stir together butter, lemon zest, and parsley in a small bowl to combine. Season with salt and pepper, to taste. Set aside.

Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add shallots and cook for 1 to 2 minutes, until softened. Add mussels, white wine, and thyme. Cover pan and cook for 4 to 5 minutes, until mussels open. Let mussels cool slightly, then remove from shells. Reserve a few shells for garnish and discard the rest.
