1. To make the tomato hummus: in a food processor, combine the chickpeas, tomatoes, tahini, oil, garlic, paprika, lemon peel, lemon juice, and salt. Process just until chunky.
2. To make the wraps: cut the firm white stalks off the collards. With a sharp knife, slice off the thickest parts of the remaining stalks that run down the backside of the leaves. Put 2 collards on a work surface, head to foot (stalk ends at opposite ends) with the paler side facing up. The leaves should overlap slightly.
3. Spread ⅓ cup of the hummus lengthwise down the center. Top with ¼ of the peppers, zucchini, and parsley. Tightly roll the leaves beginning from the bottom and tucking in the sides as you go. Cut in half on a bias. Repeat with the remaining ingredients.
