Sauté onion until cooked through. Cool and set aside. Stir together beef, onions, black pepper, Seasoning Mix, and half of beaten egg. Mix well until a paste-like consistency forms.
Coat boiled eggs evenly with flour. Take half the meat mixture and shape evenly around 1 boiled egg. Dip into beaten egg, then roll in breadcrumbs until evenly coated. Repeat each step for other egg.
Deep-fry eggs in warm oil 5 minutes until golden-brown and serve.
