Clean the Brussels sprouts and cut crosswise on the stalk. Blanch in slightly boiling salted water for three minutes, rinse immediately in very cold water and drain in a sieve.
Knead the minced meat well in a bowl with the egg, onions and 1 tablespoon corn grits, then season with salt and pepper.
With wet hands, separate 10 servings of minced meat and work a Brussels sprout florets into each portion so that each floret is well coated by the mince.
Put some corn grits in a clean bowl and roll the meatballs in it. Instead of semolina you can of course also use flour. I think it gets crispier with semolina.
Fry the meatballs in the hot fat in a pan. Then serve with side dishes of your choice.
