Drain and rinse the chickpeas thoroughly, then pat them dry with paper towels to remove excess moisture.
Slice the grape tomatoes in half, dice the cucumber into small even pieces, and roughly chop the parsley and dill.
In a large mixing bowl, whisk together the olive oil, lemon juice, grated garlic, Dijon mustard, sea salt, and black pepper until well combined.
Add the dried chickpeas, tomatoes, cucumber, pickled red onions, and olives to the bowl with the dressing.
Toss everything together until all ingredients are evenly coated with the lemon garlic dressing.
Add the chopped parsley and dill, then toss again to distribute the herbs throughout.
Divide the salad evenly among five meal prep containers with secure lids.
Label each container with the date and store in the refrigerator for up to 5 days.
