For one sandwich: Place 1 cheese slice on top of a slice of Italian bread. Spread evenly with pizza sauce. Top with another cheese slice, and spread evenly with pesto sauce. Top with another slice of cheese, and arrange 5 or 6 pepperoni slices over the top. Top with another cheese slice and finish the sandwich with a second slice of Italian bread. Spread a small amount of butter on top of the sandwich. Invert the sandwich onto a hot nonstick skillet or griddle, and cook over medium heat until browned. Spread a small amount of butter on the ungrilled side of the sandwich. Turn, and cook until brown. Serve immediately. This is one way you can use the pesto sauce we made recently. Tomorrow I will be showing you how to use pesto sauce with pasta—stay tuned! Love, Betty
