Preheat oven to 400 F.
2. Combine 1 cup wild rice with 4 cups water in a large saucepan. Bring to a boil over high heat. Reduce heat to a simmer, cover, and cook until the rice is tender, about 50 minutes. Drain and transfer rice to a large bowl.
While rice is cooking, place 1 tablespoon of olive oil in a large sauté pan over medium heat and cook the onions for 2 minutes.
Add the mushrooms, season with 1/2 teaspoon of salt and cook another 4 minutes or until the mushrooms are tender and the onions are translucent.
Remove the mushroom mixture and place in a bowl.
Heat 1 teaspoon of oil in the sauté pan and cook the chicken, garlic powder and remaining 1/2 teaspoon of salt for 3 minutes or until cooked through.
Combine all the ingredients together, place in an 8 x 8 inch baking dish and sprinkle with additional shredded cheese.
Bake for 20-25 minutes, or until bubbly.
Serve.
