In a medium saucepan, heat 1 1/2 teaspoons of the oil over medium-high heat. Add the onions and chiles and cook, stirring, for 3 minutes. Add the garlic, cumin, salt, cilantro and parsley, and cook, stirring, for 30 seconds. Remove from the heat and transfer to a blender with 1/2 cup of the stock. Process on high speed until smooth.
Heat the remaining tablespoon of oil in the pan over medium heat. Add the rice and cook, stirring, until translucent, 1 to 2 minutes. Add the puree and cook, stirring, to evaporate most of the liquid, about 2 minutes. Add the remaining stock, stir and cover, and lower the heat to medium-low. Simmer without stirring, until the rice is tender and the liquid is absorbed, 15 to 20 minutes. Remove from the heat and let sit without stirring for 10 to 15 minutes. Fluff with a fork and serve, garnished with additional cilantro.
