I made roasted butternut squash soup the other day, not from a recipe tho, just with stuff I had laying around.
I marinated the butternut squash in rosemary, garlic, lemon juice and olive oil for an hour or so, then roasted it with garlic cloves.
I boiled up onion, celery, carrot and cauliflower and seasoning with vegetable stock then simmered for half an hour. When it was cooked I added the roasted butternut squash and blended it up with a tablespoon of low fat fromage frais. It was bloomin grogeous!
