In a saucepan, bring 2 cups (500mL) of water to a boil. Add the rice. Cover, reduce heat, and simmer until the rice is tender and the liquid has been absorbed – about 35-40 minutes. Let cool.
Wash the apple, remove the core and dice into small pieces.
In a large bowl, combine the cooked brown rice with the diced apple and chopped red pepper, green onions, celery and parsley.
Combine the vinaigrette ingredients in a jar and shake well until slightly thickened. Stir into rice mixture. Cool and enjoy.
