Caprese Avocado Toast (Minus the Cheese)

Toast the sourdough bread in a pan with some butter. Once toasted, mash the avocado directly onto the bread. In a separate bowl, combine the cherry tomatoes with extra virgin olive oil, salt, and a drizzle of balsamic vinegar. Place this seasoned tomato salad mixture on top of the mashed avocado. Garnish with fresh basil. (Note: If fresh basil is unavailable, fresh arugula can be used as a substitute).
