I usually make this appetizer to use up the rest of the mushrooms before they go bad. It doesn't look very appetizing, but --YUM-- it is.
8-10 medium mushrooms, firm, closed caps
1 Tbsp butter
2 Tbsp minced onion or green onion (I just dash onion powder)
1/4 Tbsp Worcestershire sauce
1/4 c soft bread crumbs*
1/4 c shredded sharp cheddar cheese
2 Tbsp water
salt and pepper to taste
Preheat oven to 350. Wash mushroom quickly under running water; drain on paper towels. Pull stems and chop finely. Melt butter in skillet over med/low heat; add chopped stems and onion. Saute till tender. Stir in Worcestershire sauce, bread crumbs, cheese, salt, and pepper. Sprinkle salt over mushroom caps and fill with sauteed mixture, mounding over the top. At this point, you may cover and refrigerate up to 24 hours. Before serving, put 2 Tbsp water in shallow dish and arrange mushrooms in dish. Bake for about 20 min. Serve hot.
*To make soft bread crumbs: Use fork to tear apart bread on cutting board. 1 slice = 1/2 c crumbs.
