Slice bread into 1 inch slices and then cut into bite-size pieces. Alternate bread, tomatoes, and mozzarella cheese on skewers.
Combine olive oil, sweet basil, and garlic in a small bowl. Brush over skewers, turning to coat both sides. Grind peppercorns and sea salt over the skewers.
Grill on high heat for 1 to 2 minutes until bread is toasted. Turn and grill on other side, 1 to 2 minutes. Serve immediately.
Notes
TIP: If using bamboo skewers, soak in water for at least 30 minutes prior to use.
