In a medium saucepan over medium heat, warm the oil until shimmering. Add the onion and bell pepper and saute until soft, about five minutes. Add the garlic, and cook, stirring often, until fragrant, 2 to 3 minutes. Stir in the rice and cook for a minute or two, toasting a bit. Raise the heat to high, pour in the contents of the blender, and bring to a boil. Immediately reduce the heat to low, cover, and simmer until the rice is tender and most of the liquid has evaporated, 15 to 20 minutes - perhaps a bit longer if you skipped the overnight soak.
Remove from the heat and set aside to steam for 10 minutes. Immediately before seeing, fluff the rice with a fork. I like to serve topped with some crunchy nuts or any of the other toppings suggested in the post.
