Steps
1. Rinse the buckwheat groats under cold water until the water runs clear.
2. In a small saucepan, bring 1 cup of water to a boil, then add the buckwheat. Reduce heat to low, cover, and simmer for about 15 minutes until the water is absorbed and the buckwheat is tender.
3. In a frying pan, heat the olive oil over medium heat. Add the chopped onion and sauté until translucent.
4. Add the sliced mushrooms to the pan and cook until they are golden and tender, about 5-7 minutes. Season with salt and pepper.
5. Once the buckwheat is cooked, fluff it with a fork and combine it with the sautéed mushrooms and onions.
6. Serve hot, garnished with fresh dill or parsley.
