Wasabi (a fiery Japanese horseradish) is available as a paste, in tubes at many supermarkets. If you can't find it, substitute 2 tablespoons of drained horseradish.This barbecue sauce goes especially well with pork.
This is a really easy side dish. It involves only about 5 minutes of preparation (if you buy presliced mushrooms) before you put the dish in the oven. The rest of preparation time is unattended cooking, while the vegetables bake in the oven.
