Thinly slice 1 ½ lemons, and cut the remaining half lemon into 4 wedges.
Use a vegetable peeler to make ribbons out of the zucchini (this will ensure the zucchini cooks in the same amount of time as the fish).
Husk corn, and cut kernels off the cob.
Cut 4 pieces of aluminum foil double the size of your fillets.
Rinse tilapia fillets and pat dry.
Divide the zucchini ribbons and corn between the 4 pieces of foil.
Top each with 1 tilapia fillet, 1 tablespoon butter, 1 tablespoon white wine, and 2-3 slices of lemon.
Sprinkle each fillet with salt and pepper, and divide chopped basil between pouches.
With foil in front of you horizontally, bring up the two long sides and fold together tightly, leaving a little bit of space between foil and fish. Then fold up the two remaining sides to make a tight seal.
Place foil pouches on a sheet pan with the foil seam-side up, and bake until fish is tender and flaky, about 12-15 minutes.
Being careful of steam, open the pouch gently and serve with lemon wedges.
Notes
Fish cook time will vary based on size of fillets.
Foil packets can be made in advance. This is one of the reasons why foil packs are so perfect for camping trips. You can put them in a cooler, and take them to wherever you are going. If you’re cooking them at home, foil packs can be kept in the refrigerator for several hours.
If you are traveling with your foil packs, double up on the foil or use heavy-duty foil, just to make sure there are no leaks in your cooler.
