Tomato and Avocado Salsa


Slice each tomato to obtain 112-inch thick slices from the widest portion of the tomato, making sure to avoid the core. Spread 1 heaping tablespoon of mayonnaise on one half of the tomato slices. Top each with an onion slice, arugulo leaf and a second slice of tomato. Dip each sandwich into the beaten egg mixture and then the bread crumbs. Gently shake off any excess bread crumbs. Set sandwiches aside. In a large heavy saute pan, warm the butter and olive oil over medium heat. Slip each sandwich into the pan and fry until golden brown, about 3 minutes on each side. Remove and serve immediately.
