Instructions

  1. Step 1: Pat 8 oz boneless chicken thighs dry and season with 1/4 tsp sea salt and 1/8 tsp black pepper. Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat until smoking slightly.

  3. Step 3: Add 1 cup diced zucchini, 1 cup diced bell peppers, and 1/2 cup diced red onion to the skillet with 2 minced garlic cloves. Sauté for 3 minutes until vegetables begin to soften, stirring frequently.
  4. Step 4: Return chicken to the skillet, add 1/2 tsp dried oregano, and toss to coat. Transfer skillet to a preheated 400°F oven and bake for 10 minutes until chicken reaches 165°F and vegetables are tender-crisp.
