1. Spray a medium skillet with cooking spray and heat over high heat. Add mushrooms and cook and stir until mushrooms release all their liquid and begin to brown, about 7 to 10 minutes. Remove pan from heat and set aside.
2. While mushrooms cook, spray a large skillet with cooking spray and heat over high heat. Add pork, breaking it up as it cooks. Cook until pork begins to brown and is cooked all the way through, about 10 minutes. Use a slotted spoon to transfer pork to a plate and loosely cover with foil.
3. While pork and mushrooms are cooking, in a small bowl whisk together soy sauce, sake, vinegar, brown sugar, sriracha, and sesame oil. Set aside.
4. Add canola oil to pan used to cook the pork and heat over high heat. Add garlic, ginger, onion, and green beans. Stir well to coat with the seasonings. Cook until very fragrant, about 2 minutes. Add water and stir well. Cook until beans are crisp tender, about 2 minutes. Add reserved pork, mushrooms, and soy sauce mixture. Stir well to combine. Cook until most of the liquid evaporates, about 1 minute. Transfer to a platter and serve.
