Get out the puff pastry sheets and let them thaw if frozen.
Put salmon on a plate and slightly thaw it in the microwave for about 3 mins at 180watt (just pick one of the lowest settings on your micro. We only wanna help it thaw a little, not bake it)
Spread the cream cheese and herbs on the puff pastry and salmon.
If you've got an organic (unsprayed) lemon, this would be a good time to add a few slices.
Bake in a preheated oven for 20 minutes at 200°C (if in doubt check the instructions on your puff pastry)
Enjoy with a sprinkle of lemon juice!
Here's some half size salmon thingies I made to bring to a potluck :)
