Put the honey in a bowl, squeeze in the lemon juice and add the parsley flakes. Then whisk it all together with the brush that you are going to use to apply it to the salmon.
Lay the Salmon filets out on the sheet skin side down. If the filets have been skinned just look for the side that is flatter and has a pale gray stripe in the middle and lay that side down on the pan.
Brush them generously with the honey lemon mixture and cover with the lemon slices.
