Beat together, butter, dressing mix, garlic powder and cheese until well blended.
If using a loaf of bread, cut bread in half horizontally. Spread some of the butter mixture on each half of bread. If using pizza crust, spread some of the butter mixture on the top of the crust.
Put bread on ungreased cookie sheet, butter side up. Broil 4-6 inches from heat until brown. Watch carefully, it doesn't take long. Cut into pieces.
VARIATION: Slice whole French loaf into 1" slices; spread butter mix on each slice of bread, wrap sliced and buttered loaf in foil and heat in 350Â° oven for 10 minutes.
NOTE: You will have plenty of butter mix left over but it keeps well in the refrigerator for another time. Let soften before using.
