For a bridal shower I once made little heart-shaped
tea sandwiches using Valtrompia bread tubes (sold by Pampered Chef). You just put 2 pkgs of tubed croissant dough and bake them in the tubes. When they're done, you cut them into 1/2-inch slices and spoon any type of topping that you want. I think Iused pink cream cheese with a strawberry half on them, but you could make cucumber sandwiches, bacon and onion spread etc.
Appropriate for Valentine's Day, pretty, easy, and good.
