A really good one that I made for the first time is sweet potato and butternut squash.
1 onion, roughly chopped
1 butternut squash, unpeeled, halved, seeds scraped out, sliced into 2.5cm/1in x 2.5cm/1in cubes
500g/1lb 2oz sweet potatoes, unpeeled, cut into 2.5cm/1in thick rings
frylight
1 tsp ground cinnamon
½ tsp ground nutmeg
1.5 litres/2 pints 13fl oz vegetable stock
salt and freshly ground black pepper
Roast all the veg in the oven sprayed with frylight for about 45mins-1hr, once soft put into food processer and add stock, blend until smooth.
i like mine thick but you can add more stock if needed. it was very tasty and filling
