2 tablespoons olive oil
2 cups diced watermelon
1 cup feta cheese, cut into fine diced cubes
2 tablespoons minced fresh mint
4 teaspoons balsamic vinegar, or to taste
For 16 toasts
A 24-inch-long loaf of crust Italian or French bread
1 garlic clove
1/4 cup extra-virgin olive oil
In a bowl toss together watermelon, cheese, chives, mint, vinegar, and salt and pepper to taste and mound about 1 tablespoon on oiled side of each toasts.
To make toasts: Prepare grill or preheat broiler. With a serrated knife cut bread crosswise into 1/2-inch-thick slices. Combine the oil and garlic together and spread it on one side of the cut bread. Arrange bread slices in one layer in a shallow baking pan and bake in middle of oven until golden, about 10 minutes.
