Pour 3/4 cup of boiling water over 1/2 cup bulgur and let sit for 30 minutes. In the meantime, cook the brown rice and while the bulgur is cooking in the boiling water and the brown rice is cooking, go ahead and assemble the rest of the ingredients, mixing well.
When the rice is done and the bulgur has absorbed all the water, add 1/2 cup of each to the mixture and incorporate well.
