Rinse quinoa in a fine-mesh strainer. Add to a medium pot with 1 cup water and a pinch of salt. Bring to a boil, reduce to low, cover, and simmer 15 minutes until water is absorbed.
Preheat oven to 400°F. Pat chickpeas completely dry with paper towels or a clean kitchen towel.
Toss chickpeas with olive oil, garlic powder, smoked paprika, onion powder, dried oregano, and half the salt and pepper. Spread on a sheet pan in a single layer.
Roast chickpeas 20 minutes, shaking the pan halfway. Cool on the pan at least 10 minutes for best crunch.
Fluff quinoa with a fork and spread on a sheet pan to cool completely to avoid steam in containers.
Prep vegetables: dice cucumbers and bell pepper small, halve cherry tomatoes (keep cut-side up), thinly slice red onion, and chop lettuce.
Divide cooled quinoa evenly among 5 glass meal prep containers as the base layer.
Add cooled roasted chickpeas on top. Portion hummus and feta into divided compartments or separate small containers.
Layer lettuce, tomatoes (cut-side up), cucumbers, bell pepper, red onion, and olives evenly across containers.
Seal, label with prep date, and refrigerate immediately.
