Onions peel and chop finely. Drain the mozzarella. Wash the basil, dab dry and pluck the leaves from the stalk. Cut some leaves into strips. Turn the mozzarella in the lemon peel and wrap in basil leaves.
Put some leaves aside for garnishing. Knead minced meat, breadcrumbs, egg, half of the diced onions, salt, pepper and paprika. Form 8 meatballs from the minced dough, press a hollow in the middle, put wrapped mozzarella balls in it and form a meatball again.

Beat in olive oil. Coarsely chop the almonds. Mix yoghurt, lemon juice, salt, pepper, sugar and almonds. Mix tomatoes, remaining onion cubes, basil strips and the vinaigrette.
