Heat half the olive oil in a large skillet over medium-high heat. Add the mushrooms and cook until they start to brown, about 5 minutes.
Add the bell pepper, peas, and garlic to the skillet. Sauté until the vegetables are tender and fragrant, about 4 minutes.
Push the vegetables to one side of the skillet. Pour the remaining olive oil into the empty side and add the rice, breaking up any clumps. Stir everything together.
Drizzle soy sauce over the mixture and stir continuously for 3 to 5 minutes, until the rice is heated through. Adjust seasoning with additional soy sauce if needed.
Serve hot, garnished with sliced green onions.
Notes
You can substitute soy sauce with coconut aminos for a gluten-free option. Add your preferred protein such as chicken or tofu for more flavor.
