Preheat BBQ to med-high heat. Alternatively, preheat oven to 425 F. Brush chicken with a little bit of olive oil and sprinkle with salt and pepper. Grill for 7-8 min per side, or bake in an ovensafe dish for 20-25 min until chicken is fully cooked. Remove and set aside, slicing/dicing once cooled.

Meanwhile, blend all ingredients for vegan garlic mayo together in a Magic Bullet, blender or food processor. Sauce should only take 10-15 seconds on high to emulsify and thicken up.

Prepare veggies. Wash collard greens and lay open flat, gently cutting away as much of the stem in each leaf as possible. Spread with garlic mayo, then top with sliced chicken and the rest of the veggies. Top everything with avocado, then roll everything up into wraps.

I personally prefer to make my wraps smaller and then eat 2-3 of them in one sitting as opposed to having one big wrap. I find it easier to eat and fold that way, so I don't add a ton of filling to each wrap. It's up to you what you prefer - just a tip!
