Step 1

Heat oil in large saucepan set over medium-high heat. Add sausage; cook for 3 to 5 minutes or until starting to brown. Stir in mushrooms, onion, garlic and rosemary; cook for 5 to 8 minutes or until mushrooms start to soften.

Step 2

Add pasta, 1 cup of water, tomatoes and Roasted Garlic Base. Cover and bring to boil, stirring occasionally. Cook for 8 to 10 minutes or until pasta is tender but firm and most of the water has evaporated.

Step 3

Stir in half of the Parmesan, parsley and red pepper flakes. Serve with remaining Parmesan.
