- 4 cups quinoa
- 4 cups water
- 1/4 cup red wine vinegar
- 2 teaspoons salt
- 1 teaspoon ground black pepper
- 1 teaspoon lemon juice
- 4 teaspoons Dijon mustard
- 1 cup canola oil
- 2 cucumbers, peeled and chopped
- 1 green bell pepper, chopped
- 1/2 red onion, chopped
- 2 tomatoes, chopped
- 1 (15 ounce) can black olives, chopped
- Bring the quinoa and water to a boil in a saucepan. Reduce heat to medium-low, cover, and simmer until the quinoa is tender and the water has been absorbed, about 15 to 20 minutes. Scrape the cooked quinoa into a large bowl and refrigerate until cold, about 1 hour.
- Place the vinegar, salt, pepper, lemon juice, and mustard into a blender. Drizzle in the oil while blending at high speed until the dressing is thick.
- Add the cucumbers, bell pepper, red onion, tomato, and olives to the bowl with the quinoa. Pour the dressing overtop and gently fold until evenly mixed.
