To prepare the chicken, sprinkle each side of the breasts with salt, pepper, garlic powder, and oregano. Place the flour in a shallow bowl or plate, then gently dredge each piece of chicken through to lightly coat both sides, shaking a bit to remove any excess.
Set a large skillet over medium-high heat, and add just enough olive oil to coat the bottom. When pan is hot, add chicken and saute for 2-3 minutes on each side, until it’s cooked through and lightly golden.
While the chicken cooks, combine all bruschetta ingredients in a medium bowl; stir to blend.
When chicken is cooked through, remove from heat. Top each piece with generous spoonfuls of bruschetta, and drizzle with a bit of balsamic glaze, if desired. Serve immediately.
