Peel and finely dice the onion and garlic. Knead minced meat, egg, breadcrumbs, onion and garlic. Season with herbs, salt and pepper. Form 16 small balls. Put sage leaves around the chopped balls.
Fry the bacon in a pan without fat until crispy brown, remove and keep warm. Heat 3 tablespoons of oil in the pan and fry the meatballs in it all around for about 10 minutes at low heat.
Take out and let it cool down a little. In the meantime drain the corn. Clean, wash and slice the tomatoes. Quarter, clean, wash and cut the peppers into strips. Clean, wash and cut lettuce into large pieces.
Whip vinegar and 3 tablespoons of oil, season with salt, pepper and sugar. Put tomatoes, peppers, corn and lettuce in a bowl, pour the marinade over it and mix well. Put bacon and meatballs on skewers.
Arrange salad and 2 skewers on plates. Garnish with rosemary as desired. Baguette tastes good with it.
