In a large skillet on high heat, add broccoli, onion, garlic, mushrooms, red pepper, ginger, and water. Cook, stirring often until broccoli is soft and onions are translucent. Add broth and more as needed to prevent the vegetables from sticking. Stir in the carrot, cashews, vinegar, and soy sauce. Stir well and simmer for about 2 minutes. Sprinkle with sesame seeds. Serve alone or on top of quinoa or brown rice.
