Bring 2 cups of water to a boil on medium heat. Add in the buckwheat and cook for 10 minutes with the lid off, until most of the water is absorbed then turn the heat down to low with the lid on for a few more minutes until all the water is gone and the buckwheat is soft. Fluff the buckwheat up with a fork and set to cool while you prepare everything else.
Add the remaining ingredients to a large bowl, transfer the buckwheat to the bowl and toss well until all ingredients are combined
Optional: Mix in hummus before serving.
