In a large skillet, heat the olive oil over medium-high heat.
Season the chicken thighs with salt, pepper, and Italian seasoning. Once the oil is hot, add the chicken thighs to the skillet and sear for about 5-6 minutes on each side until golden brown. Remove the chicken from the skillet and set aside.
In the same skillet, add the sliced red and green bell peppers, and onion. Sauté for about 4-5 minutes until they are softened.
Add the minced garlic and crushed red pepper flakes to the skillet and sauté for an additional 1-2 minutes until fragrant.
Return the chicken thighs to the skillet, then pour in the chicken broth, apple cider vinegar, and honey, stirring to combine.
Bring the mixture to a simmer, cover the skillet, and cook for about 15 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F.
Add in the Kalamata olives and stir gently. Allow cooking for an additional 2-3 minutes to warm the olives.
Taste and adjust seasoning if necessary.
Notes
Serve garnished with fresh parsley and crushed red pepper flakes. Pair with crusty bread or over couscous/rice.
