Calico Mussels - cooking recipe

Ingredients

1/2 cup white wine
1 small onion, minced
1 lemon wedge
2 pounds mussels, cleaned and debearded
1/4 cup olive oil
3 cloves garlic, minced
1 small carrot, shredded
1/2 red bell pepper, chopped
1/2 yellow bell pepper, chopped
1/4 cup chopped fresh parsley
3 tablespoons red wine vinegar
1/4 teaspoon ground black pepper
1 pinch salt

Preparation

Combine wine, onion, and lemon in a large skillet; add mussels. Bring mixture to a simmer and steam mussels until they break open, about 5 minutes. Transfer mussels to a bowl using a slotted spoon and continue simmering wine mixture until slightly reduced, about 5 more minutes.
Remove mussels from shells, reserving some shells for serving.
Heat olive oil in a skillet over medium-low heat; cook and stir garlic until fragrant, about 2 minutes. Stir reduced wine, carrot, red bell pepper, yellow bell pepper, parsley, vinegar, pepper, and salt into garlic; cook until heated through, 3 to 5 minutes.
Mix mussels and vegetable-wine mixture together in a bowl; marinate in refrigerator, about 24 hours. Serve by scooping a mussel and marinade into reserved half shells arranged on a platter.
