Heat EVOO in a large sauté pan over medium- high heat. Once the pan is hot add Calabrian Sausage and use a spatula to break it up into 1/4" pieces.
Let the meat brown for about 2 minutes and add sliced garlic and S&P stirring occasionally; cook for an additional minute or until garlic is fragrant and slightly soft and the sausage is brown and crispy.
Turn up the heat to high and add in mussels, white wine, and first portion of basil. Simmer until mussels begin to open.
Once mussels begin to open, add butter and continue cooking until butter has fully emulsified into the liquid and mussels have fully opened.
While mussels are cooking, drizzle EVOO over baguette halves and season with S&P mix. Grill until bread is warm, toasted and has achieved grill marks.
Turn off heat from saute pan with mussels and squeeze fresh lemon juice over all the mussels. Taste and adjust seasoning of broth as needed.
To plate: Transfer mussels to a bowl and garnish with basil leaves as shown in photo. Tuck freshly-grilled bread into side of mussels as shown in photo.
