Preheat the oven to 200°C (400°F). Line two baking trays with parchment paper.
Add all of the herby mayonnaise ingredients to a bowl and mix well. Store in the fridge until ready to serve.
Add the chicken thigh, olive oil, onion powder, garlic powder, smoked paprika, red chilli flakes, ⅓ of the herby mayonnaise, and salt and pepper to a bowl. Mix well to combine. Place onto the prepared baking tray and bake for 16–18 minutes. Remove and let rest before slicing or dicing.
Lay the bacon on the second prepared tray and bake for 12–15 minutes, or until cooked to your liking.
In the meantime, prepare the avocado by mashing or according to preference.
Spread the remaining herby mayonnaise across the five burrito tortillas, then add the chicken, avocado, grated mozzarella, salt, and pepper. Wrap tightly.
Wrap in food-safe paper, aluminium foil, or food-safe bags. Eat hot, warm, or cold. Dig in.
