Preheat oven to 400 F. Peel and slice avocado. In a shallow dish, combine egg and milk. In another shallow dish, combine flour and seasonings. Place breadcrumbs in the last shallow dish.
First dip avocado in egg mixture, then in the flour mixture, then back into the egg mixture and the breadcrumbs. Place onto a large greased baking sheet. Bake for 20-25 minutes.
