We ended up eating lunch at Pizza Express today with family and friends, so didn't want a big dinner. But we wanted a little something, so I made Portabello mushrooms on toast with Stilton:
All you do is peel a large mushroom per person and spray it with oil; microwave for about 1 minute (for 2 mushrooms), then put Stilton (or other cheese, but I like Stilton) on top of the gills and put under the grill until it melts. Serve on buttered toast!
Easy, quick and delicious!
