We had a book club luncheon at my house recently, and Shelley made the yummiest sandwiches. My favorite were these...
Spread pesto on one side of bread, and toast on a griddle (pesto side down) until lightly toasted. Cut off crusts. To make sandwiches, lightly apply mayo to the inside of the bread and add thinly sliced tomatoes and avocado.
I have been craving these ever since!
