While rice is cooking, prepare the rest of the ingredients as follows: remove stems from cilantro, roughly chop then put into a food processor with garlic and onion. Process until everything is finely chopped.
When rice is cooked and still very hot, combine with cilantro mixture, salt and pepper to taste. At this point you can let sit covered for 5-10 minutes to blend flavors then serve, or bake at 350 degrees for 20 -25 minutes and then serve. Either way is good. The rice takes on a greenish hue that looks pretty. This dish goes well with Mexican dishes as a substitute for Spanish Rice.
