Begin by preparing your ingredients. Rinse the mussels in cold water and set aside. Dice the chorizo and shallot and crush the garlic.
Heat 1 tablespoon of olive oil over medium high heat. Add in diced chorizo and cook for about 1 minutes. Add in shallot and garlic and cook another 2 minutes until softened. Then add in halved tomatoes, a pinch of salt and a pinch of red pepper flakes and cook for 3-4 minutes.
Deglaze the pan with 1 cup of white wine the pour in the fresh mussels. Stir together and bring to a boil. Then place the lid on the pot and cook over medium heat for about 5-6 minutes until the mussels have opened. (Discard any unopened mussels.)
Top with fresh parsley and serve with warm crusty bread. Enjoy!
