1: Clean off mussels with a damp paper towel and inspect live mussels for dead ones. Discard the open ones.
2: In a large pan, heat oil on medium heat. Add in onion, tomato, and garlic.
3: Add in the seasonings with tomato paste and stir. Cover and cook for a few minutes until the tomatoes become soft.
4: Uncover and add in a teaspoon of sugar to reduce the acidity of the tomato.
5: Add in white wine and chicken broth. Season with salt and pepper to taste.
6: Add back in your mussels and cook covered for six minutes until they open (if using live mussels).
7: Garnish with parsley and serve.
