While the chickpeas are roasting, make the vegan tzatziki and the cucumber tomato salad.
To make the tomato cucumber salad, start by making the dressing. Mix the olive oil, lemon juice, Dijon mustard, salt, and pepper together until combined.
Next, chop the Campari tomatoes into quarters, the cucumber into thin half-moon slices, the red onion into thin slices, and finely chop the dill. Add them to a large mixing bowl and pour the dressing on top. Mix together until coated.
To assemble the pita pockets, slice each pita in half. Open the inside and smear the sides with the tzatziki. Then stuff each pita pocket with lettuce, crispy chickpeas, and a few scoops of the tomato cucumber salad.
Serve & enjoy!
