Preheat barbecue on HIGH
Reduce heat to MEDIUM. Brush a foil pan with 1 tbs of the oil. Place pan on grill and bake the mushroom caps for approximately 10 minutes.
Combine stems, crumbs, onion, parsley, red pepper, garlic and salt mix together well. Add scallops and wine to the foil pan. Sprinkle the minced mixture over all.
Drizzle the remaining oil over. Bake for 20 more minutes, or until done.
