For the salad, peel and finely dice the onion. Whisk vinegar, salt, pepper, mustard and honey. Fold in 4 tbsp. oil. Stir in diced onion.
Toast the bread in the toaster until golden brown. Wash the salad and shake dry. Clean and wash the radishes and cut or slice them finely. Mix the radishes, salad and vinaigrette. Finely dice bread slices.
For the camembert, mix breadcrumbs, flour and herbs. Whisk the eggs. Quarter the camemberts. Turn each quarter twice first in the egg, then in the breadcrumb mixture. Heat 100 ml oil in a frying pan. Fry the cheese quarters for 5-8 minutes in portions until golden brown, turning once. Sprinkle salad with croutons. Serve everything.
