Preheat oven to 425 degrees F. Thinly slice potatoes, zucchini, and lemon. Set aside.
Set 2 large pieces of parchment paper on a cookie sheet. Divide all ingredients up, place slices of potato and zucchini in first 1/3 of each piece of parchment paper (ensure there's enough room to fold paper over all ingredients & tuck all sides in after). Sprinkle salt and pepper over vegetables.
Top vegetables with salmon fillet, skin side down. Pour divided olive oil and white wine on each salmon fillet. Sprinkle salt and pepper over salmon, then divide Italian seasonings between the 2 packets. Place lemon slices on top of seasoned salmon.
To close packet, fold parchment paper over salmon and vegetables, then tuck one corner under itself, continue to fold paper at an angle so it's tightly secured. Tuck final piece of paper under whole packet so it's secure. You're essentially folding each side onto the last side you folded. That ensures it's all closed up. Refer to photo of enclosed packet for how it's supposed to look before it goes in the oven.
Place in oven, and cook for 15-18 minutes, or until vegetables are fork tender, or cut easily with your fork. Salmon will be done cooking by this point. Serve and enjoy.
