Preheat the oven to 425 degrees Fahrenheit/218 Celsius
Prepare the potato - thinly slice, and place on a baking sheet lined with parchment. Sprinkle with olive oil - about 1-2 tablespoons. Place the potato rounds on the parchment, toss and make sure both sides are coated. Then sprinkle with salt and pepper. Bake for 10 minutes. (turn after 5 minutes in order for both sides to be baked well)
While the potatoes are roasting, prepare the vegetables and season your fish. Find a 1/4 size baking sheet (or half baking sheet).
Taking a piece of parchment (a sheet large enough to sit inside a large baking sheet) situated on the baking sheet you will be using for your fish, fold it in half (hamburger style). Don't pinch the ends/sides together yet. Place the fish on one side of the parchment near the seam (make sure the fish is generously seasoned with salt and pepper). Place the zucchini, caerrot, scallon and giner on top of the fish. Salt the entire platter of food again. Then, add the splash of white wine (1-2 tablespoons).The potatoes are likely done. As soon as they are done (protecting your fingers as they will be hot), place them on top of the fish and vegetables. Then sprinkle with the herbs. Fold the parchment to meet the end. Fold both open ends once, then fold the meeting ends twice. Then begin to pleast the entire three edges all the way around. You will be amazed how once you have it in the oven and it begins to bake, the edges to stay put. Just make sure you don't see any of the edges (all are tucked under and inside of the folds and pleats, and you will be set. If you do use a paperclip or clamp of some sort, just make sure it is nothing that will melt and remember that this device will likely be very hot to the touch when you take it out of the oven.
Bake for 12 minutes. I baked a thick King Salmon fillet, and 12 minutes was enough - for one fillet, but if you are cooking larger fillets, you may want to cook 1-2 minutes more. Test with a toothpick or skewer. If it goes in easily (you don't want to overcook), then you are set to enjoy.
No need to remove the meal from inside the parchment. Simply move the parchment filled with fish and vegetables to a plate, open the parchment and enjoy with a cup of the white wine you used to bake the fish.
So incredibly simple, and absolutely satiating. I do hope you enjoy! Thank you Judith Jones!
