Sprinkle each side of the chicken breasts lightly with salt, pepper, garlic powder, and oregano.
Warm oil in a large skillet over medium-high heat. When hot, add chicken and cook for 2-3 minutes on each side, just until cooked through.
While the chicken cooks, make the bruschetta by combining tomatoes, basil, garlic, olive oil, balsamic vinegar, oregano, salt, and pepper in a small bowl. Taste and adjust seasoning as desired.
When chicken is cooked through, remove from the heat and top each piece with generous spoonfuls of bruschetta. Drizzle lightly with balsamic glaze, serve, and enjoy.
Notes
Chicken. If your chicken breasts are sliced thinly, it really helps them to cook quickly and evenly without drying out. You can buy “thin-sliced” breasts at most grocery stores, but it’s also easy to just cut thicker breasts in half through the middle so each piece becomes two.
Pro tip for chicken: Remove chicken breasts from the fridge about 15 minutes before you start cooking, if possible, to bring them a bit closer to room temperature. This helps them cook evenly without drying out.
Balsamic Glaze. You can purchase balsamic glaze at most grocery stores, or make your own by simmering 1/2 cup balsamic vinegar in a small saucepan over medium heat for 10-15 minutes. It will reduce to a thick, syrupy liquid. You can also try adding a pinch of brown sugar to the vinegar while it simmers to enhance the sweetness.
