Heat the sorghum in a microwave-safe bowl for 2 minutes. Meanwhile, warm a skillet over medium-high heat and finely chop the onion. Add the olive oil to the warm skillet along with the onions and cook, stirring, 1 minute, then add the warmed sorghum, pine nuts and salt to taste. Stir until well combined. Reserve half of the sorghum pilaf for lunch the next day, and enjoy the remaining pilaf as a side dish for dinner.
