Mash the Chickpeas: Add chickpeas to a mixing bowl and mash with a fork or potato masher until flaked and slightly chunky; similar to tuna salad texture.
Mix in the Veggies: Add red onion, celery, parsley, and pickles. Mix until evenly distributed for crunch and freshness.
Build the Creamy Dressing: Stir in vegan mayo, Dijon mustard, lemon juice, salt, pepper, and garlic powder. Adjust seasoning to taste.
Rest for Flavor (Optional): Let the mixture sit for 5 minutes to let all the flavors blend together.
Assemble the Wraps: Lay out each tortilla. Add lettuce, tomato slices, cucumbers, and spoonfuls of chickpea salad. Add avocado if using.
Roll & Serve: Roll tightly, slice in half, and enjoy immediately or refrigerate for meal prep lunches that hold up beautifully.
