Place a tall beaker on a weighing scale and pour in the ingredients for the dressing one after the other. Make a homogeneous mass with a hand blender.
Clean the lamb`s lettuce, bathe in plenty of cold water and dry with a salad spinner. Distribute on four plates. Spread some of the dressing on the leaves.
In a pan, leave the bacon cut into pieces, add the cleaned and flaky mushrooms and fry them lightly brown. Place on kitchen paper and let cool down a little.
Peel the pear and cut into small pieces. Spread over the lettuce leaves together with the bacon mushrooms and walnuts. Spread dressing on top again.
Toast the farmer`s bread in the toaster, cut into small crouton pieces. Fry in a little frying fat, add a little salt and let it get crispy. If necessary, drain a little on kitchen paper, then spread over the salad.
The dressing will keep in the refrigerator for several days.
