Season the chicken thighs with olive oil, smoked paprika, garlic powder, onion powder, salt, and pepper. Make sure both sides are well coated.
In a large skillet over medium heat, add the seasoned chicken thighs. Cook for about 5-7 minutes on each side until golden brown and cooked through (internal temperature should reach 165°F). Remove the chicken from the skillet and set aside.
In the same skillet, add the sliced bell peppers and zucchini. Sauté for about 3-4 minutes until slightly softened.
Stir in the halved cherry tomatoes and baby spinach, cooking for an additional 2-3 minutes until the spinach wilts and the tomatoes begin to soften.
Reduce the heat to low, return the chicken to the skillet, and drizzle with balsamic vinegar. Toss all ingredients gently to combine and heat through for another 1-2 minutes.
Plate your one-skillet meal and garnish with fresh basil. Enjoy!
