Peel onion and garlic. Chop the onion finely, press the garlic through a garlic press. Drain the bell peppers and also cut them into small cubes. Wash parsley, dab dry and cut into fine strips.
Mix crème fraîche, yoghurt, onions, garlic, paprika and parsley, except for a little bit for sprinkling. Season to taste with salt, pepper and a little sugar. Clean, wash and drain the rocket.
Let mozzarella balls drip off on kitchen paper. Place the egg in a deep plate and mix with salt and pepper. Put flour and breadcrumbs in a deep plate as well. Heat the oil in a small pan.
Turn mozzarella balls first in flour, then in egg and finally in breadcrumbs. Place the mozzarella balls in portions in the hot oil and fry until golden brown, turning them over. Take out immediately and drain on kitchen paper.
Serve with rocket on plates. Serve with dip sprinkled with parsley. Fresh baguette tastes good with it.
