Prepare the Chicken: Trim any excess fat from the chicken breasts and season both sides with salt, pepper, paprika, and garlic powder. Let the chicken marinate for at least 15 minutes for maximum flavor.
Cook the Chicken: In a large skillet, heat olive oil over medium heat. Add the chicken breasts to the skillet and cook for 5-6 minutes per side, or until golden brown and fully cooked through (internal temperature should be 165°F). Remove the chicken from the skillet and set aside.
Sauté Vegetables: In the same skillet, add chopped onions and garlic, cooking until softened (about 2-3 minutes). Add the bell peppers and cook for another 2 minutes until they begin to soften.
Prepare the Sauce: If using a creamy sauce, add the heavy cream and chicken broth to the pan. Stir in the cumin, thyme, and chili powder, and bring the mixture to a simmer for 5-7 minutes. If using a tomato-based sauce, add crushed tomatoes and continue to cook for another 5 minutes, allowing the sauce to thicken and flavors to blend.
Combine Chicken and Sauce: Return the cooked chicken to the skillet and allow it to simmer in the sauce for an additional 5-10 minutes, letting the chicken soak up the flavors. Optionally, add cheese on top and let it melt for extra creaminess.
Serve: Garnish with fresh herbs like parsley or basil. Serve your Chicken Eden Isle with your choice of rice, mashed potatoes, or a fresh salad.
