Rinse the rice under cold water until the water runs clear to remove excess starch.
In a saucepan, heat olive oil over medium heat and sauté the chopped onion for 2–3 minutes until translucent.
Add the garlic and rice, toasting for 2–3 minutes until lightly golden and aromatic.
Pour in the gluten free vegetable broth along with salt, pepper, and turmeric and bring to a boil.
Reduce heat to low, cover with a tight-fitting lid, and simmer the rice pilaf for 15 minutes without lifting the lid.
Remove from heat and let the rice pilaf rest, covered, for 10 minutes to steam evenly.
Fluff with a fork, then stir in chopped parsley and peas or carrots, and serve warm.
