Preheat the oven to 375°. Coat the interior of a 9x13-inch baking pan with 1 teaspoon softened butter. In a small saucepan, melt 2 tablespoons butter over medium heat. Dip the mushroom caps in the butter and place in the baking pan. Heat the remaining butter in a nonstick skillet over medium heat. Add the minced mushroom stems, celery, red onion and red bell pepper. Cook until tender, then transfer to a medium bowl. Add the remaining ingredients and mix well, then fill the caps with crab-vegetable stuffing. Bake uncovered for 20 minutes or until the mushrooms are tender and the stuffing is heated through.
