- 3 tbsp olive oil
- 1 medium, thinly sliced yellow onion
- 8 oz, sliced button mushrooms
- 2, minced garlic cloves
- 1 tsp salt
- 1/2 tsp black pepper

Instructions
- Step 1: Rinse 1 cup buckwheat groats under cold water until water runs clear. In a medium saucepan, bring 2 cups water to a boil, add the buckwheat, reduce heat to low, cover, and simmer for 15 minutes until water is absorbed and groats are tender.
