Add the wild rice blend and vegetable broth to a saucepot. Place a lid on top and turn the heat on to medium-high. Allow the broth to come to a full boil. Once boiling, reduce the heat to medium-low and allow to simmer for 45 minutes, or for the amount of time directed on the package.*
While the rice is cooking, prepare the rest of the pilaf. Dice the onion, celery, and apple.
Add the onion to a large skillet with the butter and sauté over medium heat until softened.
Add the apples, celery, sage, thyme, salt, and pepper to the skillet with the onions and continue to sauté for about five minutes more, or just until the apples and celery begin to soften (they should still have some bite).
When the rice has finished cooking, add it to the skillet with the apples, celery, and onion. Also add the chopped walnuts, cranberries, and chopped parsley. Stir until everything is evenly combined.
Taste the pilaf and adjust the salt or seasonings to your liking. Serve hot.
* You can use any brand wild rice blend. Cook according to the package directions, substituting vegetable broth for the water recommended in the instructions. Cooking time may vary depending on the brand.
