Preheat oven to 180°C.
In an ovenproof dish mix together butternut, garlic and mixed herbs.
Drizzle with olive oil.
Bake in a preheated 180°C oven for 30 minutes or until soft and roasted.
In a saucepan bring water and margarine to the boil.
Add KNORR Alfredo Pasta & Sauce packet contents, stir continuously until boiling.
Reduce heat, simmer uncovered for 8-10 minutes, stirring occasionally.
Remove from stove and leave to stand for 2 minutes.
Sauce will thicken and pasta will soften on standing.
Gently stir in the salmon and butternut to heat through.
Sprinkle with Parmesan cheese and serve with rocket leaves.
