Wash rice and drain.
In a large heavy saucepan heat the butter over medium heat. Add the onion and cook, stirring occasionally, for 3 to 4 minutes, or until just beginning to soften. Add rice, red pepper and the cumin and stir together for 2 minutes. Add the cabbage and tomato and cook for 3 minutes more, or until the mixture is thickened. Add the water and salt, increase the heat to medium-high and bring the mixture to a boil. Reduce the heat a little so that the liquid is simmering actively. Stir every minute or 2 until the rice is almost dry, then reduce the heat to very low, and stir in the green onion. Cover tightly, reduce the heat to low, and cook for 5 minutes more.
