First, combine the chicken, olive oil, balsamic vinegar, and salt in a bowl. Marinate the chicken at room temperature for 20 to 30 minutes.
In the meantime, prepare the bruschetta. Add tomato, onion, fresh oregano, extra virgin olive oil, garlic, parmesan, and sea salt to a bowl and stir until well combined. Set aside.
Next, grill the chicken according to your preferred method. We like to use a cast iron grill pan over medium-high heat on the stove and cook the chicken for about 12 to 15 minutes, flipping every 3 minutes, until done. Use a digital meat thermometer to cook the chicken to 165 degrees F, then remove it from heat.
Finally, serve the grilled chicken topped with fresh bruschetta and an additional drizzle of balsamic vinegar.
Notes
Pounding the chicken breast: Don't skip this step! Chicken breasts are often thicker on one end than the other, so pounding them thinner helps even out the thickness so that the chicken cooks more evenly. This will yield tender, juicy chicken in every bite, instead of tough edges and a juicy center.This chicken is also best served with a hearty helping of bruschetta. Pounding each chicken breast thinner will give you more surface area for the topping, which in turn provides a better ratio of chicken to bruschetta in every bite.Balsamic vinegar: Don’t use the fanciest or most expensive balsamic you own for this recipe, since it's going in a marinade. We recommend using something that’s middle-of-the-road in terms of quality and price. You want a clean, bold flavor, but you don’t need to spring for something that should only be enjoyed with some olive oil and freshly baked bread.Fresh oregano: This bruschetta gets an additional pop of flavor from fresh, finely chopped oregano. If you don't have it, don't replace it with dried oregano from the spice rack - the flavor won't be the same. You're better off skipping this ingredient if you have to. (But we highly recommend you don't skip it if you can buy fresh oregano at the store, or grow your own herbs!)Serving suggestions: You can round out your dinner with side dishes like our easy smashed potatoes, roasted veggie risotto, or oven roasted parmesan green beans. Any starch, vegetable, or salad (or combination thereof) goes great with this healthy, high protein dinner!
