You will need four sheets of foil about 15 inches x 12 inches. Fold each sheet in half. Starting at one end of the folded edge cut a half of a heart shape in such a way that when the foil is opened it is in the shape of a heart.
Place the olive oil, capers, caper liquid, maple syrup, salt, oregano, pepper and fennel seed in a bowl and whisk until blended.
Place 1/4 of the beans in each pouch, in the center of one half of the foil. Center them on one side of the cut heart so that the other side will fold over the top of the filets easily. (Do this for all four pouches.)
Add 1/4 of the diced zucchini in each pouch.
Rinse the fish filets in cold water and pat dry. Put the filets, one in each pouch, on top of the beans.
Scatter 1/4 of the tomatoes and olives evenly over the fish in each pouch.
Pour 1/4 of the olive oil mixture over the fish in each pouch.
Add 1 tablespoon white wine to each of the pouches by pouring it over the beans.
Close the foil by rolling the edge inward, starting at the point of the heart and working around to the base of the heart. The foil pouch with the fish inside will be in the shape of a large half circle.
Preheat the oven to 325°F.
Place the pouches on a cookie sheet and then into the oven. Cook for about 12 to 15 minutes.
To serve, remove each pouch to a plate and let stand 30 seconds before cutting the pouch open and eating directly from the open pouch. There will be some hot steam that escapes when the foil is cut, so be careful.
