Pound the chicken into thin pieces (approximately 1 cm) and set aside.
Using a food processor, combine the cashews and poultry seasoning and process until fine. Don't process for too long or cashew butter will form. Leave some chunks for texture. Place in a flat container for 'crumbing'.
Pour the almond milk into a flat container.
For each piece of chicken, place in the almond milk, then the cashews and then on a wire rack on top of a baking tray.
Once each piece has been 'crumbed', place the baking tray in a pre-heated oven at 350F for 20 minutes.
For the sauce
Mix all ingredients in a small mixing bowl until well combined.
For the topping
Mix all ingredients together.
To assemble
After 20 minutes of baking, take the chicken out of the oven.
Spread the sauce on one side, place a slice of prosciutto on top, then the avocado topping.
