Preheat oven to 325ºF.
Combine the rice, green onions, pineapple, edamame, tofu, and cashews on a sheet pan. In a small bowl, whisk together the oil, soy sauce, and sriracha. Pour the oil mixture over the rice mixture and toss to coat.
Bake the rice for 45-60 minutes, stirring about every 20 minutes, or until the rice is mostly dry and beginning to get crispy near the edges of the pan. Serve with additional soy sauce and sriracha, if desired.
