In a medium sized pot, bring 3 cups of water to a boil with a 1 tsp of salt. Add the rinsed rice, cover, reduce to a light simmer and cook for 15-20 minutes until the rice is tender. You can use another method to cook the rice, such as an Instant Pot or rice cooker if you prefer. The rice is best prepared the day before and stored in the fridge overnight.
In a large skillet or wok over medium heat, heat half of the sesame oil then add half of the mushrooms and cook for 3-5 minutes until mushrooms are golden brown and crisp. Transfer to a plate and do the following with the remainder of the sesame oil and mushrooms.
Once all the mushrooms are cooked, add 1 tbsp olive oil to the same pan sand sauté the ginger, garlic, green onion and chilli flakes, stirring frequently until fragrant, about 1 min.
Turn the heat up to medium high heat and add the cooked rice, soy sauce or tamari and salt, cooking and constantly stirring for roughly 3 minutes.
Add the cooked mushrooms, snap peas and frozen peas and stir fry for an additional 2 minutes, stirring often.
Remove from heat and serve hot with chopped fresh green onion and toasted sesame seeds.
