Preheat oven to 450 degrees. In a small saucepan, combine soup mix and water; heat to boiling. In
another saucepan, melt butter over low heat and blend in flour and pepper. Gradually stir in hot soup and
cook until thickened. Add tuna and fold in peas. Pour into a greased baking dish and top with bread
crumbs. Bake for about 15 minutes, until heated through.
