Trim crusts from bread, and flatten slightly with a rolling pin
In a bowl, stir blue and cream cheeses together with the egg until
well blended and creamy.
Spread a thin layer of cheese mixture
over each slice of bread. Roll one asparagus spear inside each, and
fasten with a toothpick.
Melt butter in a small saucepan. Roll each asparagus wrap in butter
to coat.
Place on a baking sheet small enough to fit into the freezer,
and freeze for one hour, or until butter hardens and wraps are
somewhat firm
Remove pan from freezer, discard toothpicks, and
cut each wrap in half crosswise. Store in a resealable plastic bag in
the freezer until ready to use.
To serve, preheat oven to 400 degrees F (205 degrees C).
Arrange frozen asparagus wraps on an ungreased baking sheet.
Bake in the preheated oven for 25 minutes, or until lightly browned.
Check occasionally, and turn if necessary, for even browning and to
prevent burning. Enjoy!
