1. Heat a medium saucepan over medium-high. Add 1 tbsp oil, then buckwheat. Cook, stirring often, until toasted and fragrant, about 2 min. Cover with 1 in. water. Bring to a boil, then cover and reduce heat to low. Cook until buckwheat is just tender, 12 to 13 min. Drain and rinse under cold water.
2. Whisk remaining 6 tbsp oil with vinegar, honey and 1/2 tsp salt in a large bowl. Season with pepper, then stir in olives and onion, and let stand.
