1 loaf firm white bread, unsliced
1 (3 oz.) pkg. cream cheese
1/4 lb. sharp cheddar cheese
1/2 c. butter, 1 stick
2 egg whites, stiffly beaten

Trim crusts from bread. Cut bread into 1 inch cubes. Melt cheese and butter in top of double boiler over hot water until of rare-bit consistency. Remove from heat. Fold in beaten egg whites.

Dip bread cubes into cheese mixture until well coated. Place on cookie sheet. Refrigerate overnight.

Bake in hot oven (400 degrees) 12-15 minutes or until puffy and golden brown. Makes about 4 dozen.
