Place your sliced mozzarella cheese, basil and tomatoes on a slice of bread. Sprinkle some salt and pepper, then drizzle with a bit of olive oil and/or balsamic vinegar, or spread the bread with Garlic Basil Mayo before putting ingredients on the bread. Top sandwich with second slice of bread and cook in a panini maker or on the stove in a skillet with another skillet on top (see below for my oh-so-fancy technique) over medium heat. When side 1 is lightly browned, flip and cook until side 2 is browned and the cheese is melted.
