First, cook the rice (separately) according to package directions, using chicken stock instead of water.
Meanwhile, melt butter and sautee the apple and onion until soft, for 3 or 4 minutes. Let them cool.
Once the rice is cooked, combine all 3 different kinds of rice in a bowl and mix gently. Add the apple and onion mixture, and the cranberries. Toss until combined.
Check for seasoning, you may need to add salt - depending on how you seasoned your rice originally.
Sprinkle the scallions on top of the rice before serving.
Eat warm.
Notes
You may substitute your favorite wild rice for the seperate rices if you prefer.
