Heat a large pot over medium heat with avocado oil. When hot, add the onion and garlic and saute, gently, until the onion is softened, 2 to 3 minutes.
Add the rice to the pot and toast, stirring, until fragrant and a golden brown color, about 4 minutes.
Add tomato sauce, water, cumin, kosher salt and pepper and stir to combine. Bring the contents in the pot to a boil. Once it reaches a boil, reduce heat to low, cover and cook for 10 minutes.
When the 10 minutes is up, add the frozen peas to the pot and continue to cook until the rice is tender and the peas are cooked through, about 10 more minutes.
When ready, fluff the rice with a fork. Taste and add more salt, if desired. Serve and enjoy!
