Heat oil in a sauté pan over medium heat. Add onion and sauté, 5-7 minutes.
Add silan to the sautéed onion. Keep mixing so that the silan doesn’t burn.
Add assorted sliced mushrooms. Mix and season with the soy sauce, salt and pepper and umami powder.
Cover and continue to cook over medium heat. Mix from time to time, for about 20 minutes or until mushrooms are tender.
Meanwhile, microwave the rice pouch as per package instructions. Add rice to the pot and mix to combine. Serve immediately or set aside for a later use. You can warm up the rice in the oven or keep it on a warm spot on the hot plate.
