Thoroughly clean the mussels under cold water, scraping off any debris with a brush. Discard any mussels that are open and don’t close when tapped.

In a large skillet or sauté pan, heat 3 tablespoons of olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.

Season the peeled and deveined shrimp with salt and pepper, then add them to the skillet. Cook until they turn pink, about 2-3 minutes, stirring occasionally.

Once the shrimp are cooked through, add the cleaned mussels along with red pepper flakes. Stir well to coat, then cover the skillet with a lid.

Let the mussels cook for approximately 5-7 minutes, until they open up. Discard any mussels that remain closed.

Remove from heat and garnish with freshly chopped parsley. Serve immediately with crusty bread or pasta to scoop up the tasty sauce.
