Break an egg at the narrow end, remove the yolk and egg whites, and keep chipping away at the shell until there is an opening about the size of a half dollar. Rinse out the egg shell and let it dry. Then cut a small piece of wheatgrass that will fit into the egg shell. You may need to chip away more of the egg shell to fit in all the roots. Then write each guest's name on the egg shells, and place them in an egg cup.
