Finely slice the onion and fry in the butter (or vegan margarine), along with
the finely chopped sage and halved chilli. Cook until the onions are
soft.
Roll out two sheets of tin foil over lapping each other in a cross
formation. Peel and slice the butternut squash into four and place on the foil.
Add the fried onion, chilli and sage, then sprinkle on the pistachio nuts.
Drizzle with maple syrup and olive oil then toss the butternut squash until
coated evenly. Pull the sides of the foil up to form a sealed bag, this will
allow the the butternut squash to cook in its own juices and the pick
up the rest of the flavours perfectly.
Cook for 45 minutes at 200c, serve warm on a bed of mixed leaves dressed
with the balsamic vinegar.
