First trim and dice the chicken thighs into bite size pieces.

Place the chicken pieces in a large bowl

Add in the garlic powder, onion powder, smoked paprika and 1/2 tsp salt. Stir to evenly coat the chicken with spices.

In a large skillet heat the olive oil over medium high heat. Add the chicken and brown for about 10 minutes or until the chicken pieces are browned on all sides and mostly cooked.

In a medium size bowl combine the chicken broth, tomato paste, Diet coke, and Balsamic vinegar stir until well mixed.

Pour the mixture over the chicken and bring to a low boil over medium high reduce to medium and simmer for about 15-20 minutes until the sauce has reduced and thickened and the chicken is cooked through.

The sauce reduces the longer it simmers so if you prefer a thicker sauce cook longer, for a thinner sauce just cook until the chicken is thoroughly cooked.

If you want the sauce to thicken more reduce the heat and simmer over low until the desired thickness is reached.
