Season chicken breasts with salt, pepper, and dried oregano on both sides.
Heat olive oil in a large skillet over medium-high heat.
Sear chicken for 5-7 minutes per side until golden brown and an internal temperature of 165 degrees Fahrenheit is reached. Remove chicken and set aside.
In the same skillet, add minced garlic and sauté for 30 seconds until fragrant.
Pour in balsamic vinegar and honey, stirring to deglaze the bottom of the pan.
Add cherry tomatoes and simmer for 3 to 5 minutes until the sauce reduces slightly and tomatoes soften.
Return chicken to the skillet, basting thoroughly with the balsamic glaze.
Garnish with fresh basil and serve immediately.
