I put the entire thing together while my husband was putting our daughter to bed the other night. It took about 15 minutes to assemble, and another 20 or so to cook!
Fish of choice, I used tilapia fillets
1 tsp dried oregano per fillet
Lay your fish fillet down over the lemons, and sprinkle with your seasonings, and Kosher salt. Try to make it an even covering.
Lay down the fresh dill, or herb of choice, top with the butter, and wrap the parchment paper up tightly. To start off with, with the long side, fold the paper together, a few times over, like a lunch bag, so that you have a tight seal.
Holding the seam down, fold the ends up, so that the fold wraps under the fish packet, again like a lunch bag. This will keep the packet from unfurling in the oven, and trap the steam in the packet. Fold up one end, and before you fold the other end, pour in about 1/2 C of the dry white wine; don't worry, if you've wrapped it up properly, the wine will stay in the packet. Once the wine is poured in, wrap up the other end the same way.
Place your packets of fish on a baking tray, place into a preheated 400* oven, and bake for 20 minutes. This will smell amazing, and make for a very impressive presentation - it's so fun to open these at the table!
