Heat a large skillet over medium heat. Add a drizzle of olive oil and once hot, add the chicken. Season with salt + pepper. Cook until the chicken is browned all over and cooked through, about 5 minutes. In a small bowl, whisk together the balsamic, honey, dijon, oregano, thyme and crushed red pepper. Slowly pour the balsamic mixture into the skillet with the chicken. Cook until the balsamic thickens and coats the chicken, about 5 minutes. Watch close, you don't want to cook the sauce so much that it ends up sticking to the bottom of your pan. Once the sauce has thickened, reduce the heat and toss in the brussels sprouts. Cook for another 3-5 minutes or until the brussels sprouts have just begun to cook down. Remove from the heat and stir in the basil + lemon juice.
