Step 1Toss together chicken chunks, oil, garlic and cloves in 2 1/2-quart casserole dish or microwave-safe bowl. Cover with plastic wrap and microwave on high power until chicken is no longer pink, about 5 minutes. Remove chicken to separate bowl and discard cloves. Keep chicken warm.
Step 2Add carrots, celery, onion and broth to casserole and cover with lid or plastic wrap. Cook on high power until vegetables are tender, about 10 minutes. Add tomatoes, beans, wine, salt, pepper and thyme. Cover and cook until mixture bubbles, 10 minutes. Stir to mix all ingredients. Add reserved chicken and microwave at high power until all ingredients are hot and flavors combined. Add spinach and cover until spinach wilts, 3 minutes.
