Pre-heat oven to 200°C (390°F) (unless cooking with tomatoes - see details with tomato cooking instructions).
Chop mushrooms into bite size pieces. Place into an oven proof dish. Drizzle with olive oil and add 2 tbsp of vegan margarine to dish. Put in oven for 20 – 30 minutes. Stir after 10-15 minutes to make sure none of the pieces of mushroom are getting dry.
