Use the amount of water for the rice according to instructions on the package. Typically straight brown rice is 1:2 ratio rice to water. Straight wild rice is a ratio of 1:3 of wild rice to water. Make sure to follow the directions on the package on how to cook the rice on the stove top.
Bring the rice, ½ teaspoon of salt, butter, and water to a boil. Reduce the heat to low, cover, and cook 50 minutes. Do not stir or uncover during this 50 minutes.
Once done, remove the pot from the stove and let it sit, covered for 10 minutes. Then uncover and fluff with a fork and allow to cool.
In a medium sized serving bowl, gently mix the rice, pecans, and green onions.
In a separate container with a lid, mix the lemon juice, olive oil, orange juice and zest, sugar, and salt and pepper to taste.
Just before serving, mix the citrus vinaigrette into the rice mixture. Serve warm, chilled, or at room temperature.
