This delicious stew of chicken, tomatoes, and mushrooms takes very little time to prepare and cook.
In a 2 1/2-quart microwave-safe dish with a lid, combine mushrooms, garlic, oil, and 1/4 cup water; season with salt and pepper. Cover, and microwave on high, 2 minutes.
Stir in tomatoes, orange zest, rosemary, cayenne, and chicken until combined. Cover; microwave on high until chicken is just cooked through, 12 to 14 minutes. Remove orange zest, and serve.
