5 slices Texas toast (English toasting bread sliced 1 inch thick)
1 pkg. (3 oz.) cream cheese
1/4 lb. Cheddar cheese
1/2 c. butter
2 egg whites

Trim crust from bread. Slice each piece into 9 cubes. Melt Cheddar cheese, cream cheese and butter over very low heat. Cool. Beat egg whites until very stiff. Fold into cooled cheese mixture. Dip each bread cube in cheese-egg mixture. Place on cookie sheet and refrigerate for at least one hour or overnight. Bake 400 degrees 12-15 minutes. (Can be frozen up to 3 months before cooking.)
