Preheat the oven to 425 degrees and line a baking sheet with parchment paper.
Dry the chickpeas off with a clean kitchen towel and add them to a food processor. Pulse until they start to turn into crumbs - don't over-blend or they will turn into mush.
Place the chickpeas on the baking sheet with the oil & dry seasonings. Toss to coat and spread out evenly. Place in the oven for 15 minutes. Toss and cook for another 5 minutes - being sure to keep an eye on them so they don't burn. Remove from the oven.
Add all of the dressing ingredients to a food processor or blender and blend until smooth. Taste and adjust the seasonings as needed. Set aside.
Cut the ends of the lettuce off and rinse the lettuce leaves under cold water. Dry off and place in a large bowl. Pour over enough dressing to coat the lettuce and toss to combine.
Transfer to a serving platter and top with the breadcrumbs, avocado and vegan parmesan.

Notes
If you're not planing to eat this all at once, I would only add dressing to the amount you plan to eat. Save the rest for leftovers.
For garlic toast: slice a baguette and add olive oil, garlic powder and garlic salt to one side of each slice. Toast in the oven or air fryer at 370 degrees until browned.
