Fish and Vegetable Foil Packets

Preheat the oven to 400 degrees F (200 degrees C). Cut 4 squares of aluminum foil.

Place 1/2 cup zucchini in the center of 1 piece of foil. Add 1/4 cup potatoes and 1 cod fillet; season with salt and pepper. Layer with 1/4 of the onion slices, 1/4 cup tomatoes, and 1/4 of the basil. Fold foil over vegetables, crimp edges to seal tightly, and place on a baking sheet. Repeat to make remaining packets.

Bake in the preheated oven until vegetables are tender and fish flakes easily with a fork, about 20 minutes.
