Fresh Mozzarella, Tomato, and Cracked Black Pepper on Focaccia

These panini are so simple to prepare and so delicious, that they should become a summer staple when tomato season is in swing. Use only fresh mozzarella and luscious, juicy tomatoes. If you can't find focaccia, try country bread-just toast the slices in the oven at 350 degrees Fahrenheit for 5 minutes. (If the slices are too big, cut the 6 slices in half before toasting. These are the best bite sizes.) When the ingredients here are at their peak, all in top form, these are true works of art.
