Add the olive oil to a large nonstick skillet set over medium heat. When hot, add in the onion and cook for about 2 to 3 minutes, until it starts to soften.
Stir in the mushrooms and broccoli. Cook for about 5 to 7 minutes, until the broccoli is crisp tender.
Stir in the garlic and cook for 30 seconds, until fragrant. Add the cold rice to the skillet and cook, stirring frequently, for 3 to 4 minutes, until fried and hot (using a wooden spoon to break up the clumps as it cooks).
Remove from the heat and stir in the peanuts and soy sauce.
Serve with desired garnishes.
Notes
Recipe time does not include time to cook and chill the rice. Be sure to plan ahead.
