Prepare the whole wheat couscous according to the package instructions, adding a pinch of salt to the cooking water. Fluff with a fork and allow it to cool slightly.
While the couscous cooks, prepare the vegetables. Roughly chop the cucumber, dice the bell peppers, finely chop the red onion, halve the cherry tomatoes, and chop the parsley.
Make the dressing by whisking together olive oil, lemon juice, vinegar, oregano, smoked paprika, salt, and black pepper in a small bowl or jar.
Add the drained chickpeas to a bowl and toss with 1 tablespoon of the dressing for extra flavor. For crispier chickpeas, roast them in the oven at 350°F for 20 minutes.
In another bowl, combine the bell peppers, red onion, parsley, and 2 tablespoons of the dressing.
Divide the couscous evenly among meal prep containers.
Arrange the cucumber, tomatoes, pepper mixture, olives, chickpeas, and a generous spoonful of hummus on top.
Divide the remaining dressing among the containers. Mix before eating for the best Mediterranean Lunch Box Meal Prep experience.
