Cook the Quinoa: Rinse the quinoa thoroughly. Simmer in vegetable broth or water for 12–15 minutes until fluffy. Drain any excess liquid and spread onto a flat surface to cool completely.
Prepare the Base: In a mixing bowl, combine the cooled quinoa with rinsed, canned chickpeas.
Add Freshness: Fold in diced cucumber, cherry tomatoes, and finely chopped red onion.
Whisk the Dressing: In a small, separate container (to be packed with the box), whisk together 1 tablespoon of extra virgin olive oil, 1 teaspoon of lemon juice, dried oregano, salt, and pepper.
Assemble: Add the quinoa salad mixture to your bento box. Top with a sprinkle of crumbled feta cheese if desired.
Pack the Dressing: Place the small container of dressing inside the bento box. Instruct the reader to drizzle the dressing over the salad only just before serving to maintain ingredient crunch.
