I make chicken nuggets from Annabel Karmel which is a similar method to this and it always gets great comments when I cook them for kids parties.
In the Annabel Karmel recipe you marinate the chicken in milk, lemon juice, garlic and thyme for 4 hours or overnight (in the fridge). The coating uses Rice Krispies (Rice Bubbles) and grated parmesan which would be easy to add into the thermomix. She suggests adding a teaspoon of oil to the coating mix, then you can oven bake the nuggets (or I shallow fry).
Also can vary marinade to use oregano/thyme and paprika, cayenne or tabasco. Hope this gives someone ideas of flavour variations.
