Season the chicken breasts evenly on both sides with salt and black pepper.
Heat olive oil in a large skillet over medium-high heat.
Place chicken in the skillet and sear for 5 to 7 minutes per side, or until the internal temperature reaches 165 degrees Fahrenheit.
Remove chicken from the skillet and set aside on a plate.
Reduce heat to medium and add minced garlic to the skillet, sautéing for 60 seconds until fragrant.
Pour in balsamic vinegar, honey, and dried oregano, whisking to combine and scraping any browned bits from the pan.
Simmer the mixture for 3 to 5 minutes until the liquid has reduced by half and thickened into a glaze.
Return the chicken to the skillet and turn to coat thoroughly in the glaze.
Serve immediately, spooning extra glaze over the chicken.
