Preheat oven to 400F. In a small bowl, stir together goat cheese, 1 Tbsp. parsley and pepper until thoroughly combined. In a medium bowl, stir together tomatoes, 2 tsp. olive oil, salt and 1 1/2 tsp. parsley.
Slice off and discard ends of bread. Slice loaf diagonally into 1/2-inch-thick slices and place on a baking sheet. Toast in oven until golden brown, about 5 minutes. Rub 1 side of each toast slice with cut side of garlic.
Brush with remaining olive oil.
Just before serving, spread toast slices with cheese mixture and top with tomato mixture.
