Cut the mushrooms in half (if smaller) or in quarters (if big).

Put oil or melt butter (don't forget to add a bit oil in the butter so it doesn't burn) in a pan and place mushrooms. Fry them with closed cover until they become light brown in colour and soft.

Remove the pan and add the mixed spices, salt, pepper and put mustard over the mushrooms (ammount by choice). Mix everything nicely and fry the mushrooms for 5 more minutes while mixing them constantly.

Put the mushrooms in a large plate. Slice the gherkins in squares and mix them with the mushrooms. Squirt lemon juice over the sallad.

Decorate with lemon slices which can be used later (if someone wants a more sour taste).
