First, make the herb butter. Place the butter and herbs in a bowl and with a fork, mix properly. Wrap the butter in cling wrap and turn into a “sausage”. Keep in the fridge or freezer until needed.
Cut two pieces of baking paper about 30 x 30 cm. Place 2-4 onion rings in the middle of each piece of paper. Place the beans or asparagus on the onion rings.
Top it with the trout portions.
Lastly add a slice of lemon and cut the butter into two discs. Place a disc of butter in each parcel. Before closing the parcel completely, add the wine to each parcel and close.
