Focaccia is a flat, round Italian bread with a dense texture that slices perfectly for sandwiches. Look for focaccia in the grocery store's bakery or deli, or stop by an Italian bakery.
Freeze any remaining pesto to use on pasta or crostini, or to add a flavor-boost to sauce, soups, eggs and rice. Drop pesto in 1- to 2-tablespoon portions onto a waxed paper-lined cookie sheet; freeze until firm. Transfer the frozen pesto portions to a food storage freezre bag. Remove only what you need, then return the resealed bag to the freezer.
