Preparation:

1. Cut onion and zucchini in slices, peppers in long strips. Peel garlic and chop finely.
2. Remove sausage from casing and break into 1 inch pieces.
3. Heat olive in a heavy pan to medium/high heat, stir fry vegetables except garlic for 2 minutes. Add garlic and cook for 1 more minute. Salt and pepper to taste. Remove everything from pan with a slotted spoon and set aside.
4. Fry sausage pieces for 2-3 minutes, adding some olive oil if needed- until cooked through and crispy. Remove from pan and add to vegetables.
5. In the meantime bring 3L of water to a boil and add salt to taste. Cook pasta al dente.
6. In a dry pan heated to medium high heat toast pine nuts to golden brown. Remove from pan immediately.
