Chop the anchovies very finely and process into a dressing with mayonnaise, lemon juice, mustard and 1 tablespoon water. I let everything turn in the mixer so that no pieces of anchovy can be seen in the dressing.
Cut the toast slices into 2 cm cubes and mix with a little oil. Then fry into crispy croutons. Fry the bacon until crispy. Cut the chicken breast into strips, season with salt and pepper and also quickly fry all over until crispy. Cut the spring onions into rings.
Mix half of the onions and the meat with the dressing. Wash and pluck the lettuce and mix with the dressing. Scatter the bacon, croutons and the remaining onion rings over the salad.
