Toast the bread, spread with butter and cover with salmon. Remove the stems from the mushrooms, fill the heads with a little bit of herb butter and cook in the stove at 180 degrees for about 3 to 4 minutes. Spread evenly on the smoked salmon.
Toast about 1 to min in the stove form until the salmon is warm.
Our tip: As an alternative to fresh herbs, you can also use frozen ones – they also stand out for their fresh taste!
