Prep the chicken: Season chicken breast pieces with ½ teaspoon salt and ¼ teaspoon black pepper.
Brown the chicken: Heat 1 tablespoon of olive oil in a large Dutch oven or heavy pot over medium-high heat. Add the chicken and cook for 4–5 minutes, until lightly golden but not fully cooked through. Remove and set aside.
Sauté aromatics: Add the remaining tablespoon of olive oil to the pot. Stir in the onion and cook for 3 minutes until softened. Add garlic and cook for 30 seconds until fragrant.
deglaze the pan with the red wine waiting until fully absorbed before proceeding
Add vegetables: Stir in the bell peppers, eggplant, zucchini, and potatoes. Cook for 5–6 minutes, stirring occasionally, until the vegetables begin to soften.
Build the stew: Add the cherry tomatoes (or canned tomatoes), chicken broth, oregano, basil, crushed red pepper flakes (if using), and remaining salt and pepper. Stir well, scraping up any browned bits from the bottom.
Simmer: Return the chicken to the pot. Bring to a gentle simmer, cover, and cook for 20–25 minutes, stirring occasionally, until the vegetables are tender and the chicken is cooked through.
Finish & serve: Taste and adjust seasoning if needed. Garnish with fresh parsley or basil. Serve hot with crusty bread to soak up the flavorful sauce
