Rinse chops in cold water and pat dry. Heat the oil in a large pan with an ovenproof handle (at least 30 cm Ø), fry the chops briefly on both sides. Season with salt and garlic pepper.
Remove meat from the pan and set aside. Fry the potatoes in frying fat for a few minutes until golden brown. Add paprika and onions, fry briefly. Cut tomatoes a little smaller. Add beans, canned tomatoes and tomato juice to the vegetables and bring to the boil once.

Garnish with parsley.
