Balsamic Chicken with Peppers

This picture doesn't do this dish justice! I tried this because a dear friend bought me a lovely bottle of lemon balsamic vinegar for my birthday, and I thought the flavors would compliment the ingredients in this dish. I served this with some couscous and it came together in under 30 minutes.1 lb chicken breasts
1 each: red bell pepper, yellow bell pepper, large onion : sliced thin
3 tbsp thyme leaves
2 tbsp chopped basil
4 tbsp balsamic vinegar
4 tbsp olive oil
kosher salt and fresh ground black pepper

Sprinkle each side of chicken breasts generously, with salt and pepper. Heat 2 tbsp oil in large saute pan over med-high heat. Cook chicken breasts until golden brown, flipping once, for about 8 minutes. Remove from pan and set aside. Add remaining oil and saute the peppers and onions
for about 3 minutes. Deglaze the pan with the vinegar, scraping up the bits on the bottom of the pan. Add the herbs and continue to cook about 4 more minutes. Return chicken to pan, and spoon the mixture over the chicken and cover pan. Simmer on med-low heat for about 4-5 minutes, or until chicken is cooked through.
