In a medium saucepan, combine cherry filling, onion, basil and oregano; mix well. Cook, stirring constantly, over medium heat 5 minutes, or until mixture is bubbly and flavors are blended. Let cool to room temperature.
In a small bowl, combine garlic and olive oil. Brush both sides of each bread slice with oil mixture; place on an ungreased baking sheet. Broil, 4 to 5 inches from the heat, 1 to 2 minutes per side, or until golden brown.
Top each slice of bread with a generous tablespoon of cherry mixture. Serve immediately as an appetizer or first course.
