Try this:
butternut squash, red onion, red and green peppers, sweet potatoes - peel/cut into equal size chunks. Place in roasting tin, pour over good olive oil, add loads of good strong herbs - thyme, marjoram, etc. Season. Roast in hot oven for 20 mins. Add 'chunks' of tomamatoes and a few mushrooms, also cut into pieces. Finish for another 15 mins.
Turn onto plate, add rice - cook the rice in stock for extra flavours by the way - and eat with a nice crusty bread to get the juices.
Filling, tasty and looks nice too...
