Instructions
- Step 1: Rinse 1 cup buckwheat groats under cold water until water runs clear, then drain.
- Step 2: In a medium saucepan, bring 2 cups water to a boil. Add 1 tsp salt and the rinsed buckwheat. Reduce heat to low, cover, and simmer for 15 minutes until water is absorbed and buckwheat is tender. Remove from heat and let sit covered for 5 minutes.

- Step 4: Add 10 oz sliced button mushrooms to the skillet with the caramelized onions and sauté for 6-7 minutes until mushrooms are browned and tender.
- Step 5: Stir in 2 minced garlic cloves, 1/2 tsp ground coriander, and 1/4 tsp ground black pepper. Cook for 1 minute until fragrant.
- Step 6: Fluff the cooked buckwheat with a fork and add it to the skillet with the onion and mushroom mixture. Stir in 1 tbsp butter and 2 tbsp chopped fresh dill. Mix well and adjust seasoning with salt if needed.
