Many thanks to Jamie Oliver for suggesting this comfort food wonder!
Peel and chop the onions, carrots, garlic and celery. Pick and chop the rosemary.
Heat 2 tablespoons of olive oil and gently sweat the veggies in.
Halve, de-seed and chop the squash (I hate this part). Then add the squash and stock in the pan, bring to boil and simmer for about 30mins.
When the squash is tender whiz the soup with a stick blender and season it to perfection.

Grill the pancetta until crisp and scatter over the soup.
Melt the cheddar on the crostini and serve alltogether.
