– Prep all the ingredients. If you want to add some smoky flavor grill lemons at least one hour prior to cooking dinner so they are easy to handle and you avoid getting burned. Be careful the juices will run easily when you remove them from the grill, use tongs and place lemons in a heat resistant bowl.  Make sure the shrimp are cleaned and deveined and the mussels and clams are rinsed well. – Cook the pasta 1 minute shy of package directions.   You will finish cooking it in the sauce. Before straining reserve 1 cup of pasta water for later. – Brown the Italian sausage once it is fully cooked add cherry tomatoes, shallot, mushrooms, thyme, garlic, salt, and pepper. Allow the vegetables to cook over medium low heat until tomatoes start to burst.
