PREPARATION:

Fish In A Foil Pouch:

1. Preheat the oven to 375 degrees F.
2. Combine zest with spice blend. Spread the spices evenly on both sides of each fish fillet.
3. Fold four 14-inch squares of heavy-duty aluminum foil in half forming 4 rectangles. Assemble the packets by dividing ingredients evenly. Place onions in a single layer, followed by the squash, zucchini, and fennel. Place the fish on top; add tomatoes and drizzle with olive oil.
4. Garnish with basil leaves. Fold foil over ingredients; seal the edges by folding or crimping.
5. Place the packets on a baking sheet and place in the oven. Cook, undisturbed, until fish is just cooked through and flakes easily, 18 to 20 minutes, depending on the thickness of the fillets.

To Serve:

1. Remove from grill. Open packets carefully, and transfer to wide, shallow serving bowls.

RV Livin' Spice Blend:

1. In a spice grinder, grind the rosemary and the anise seed into a powder. Transfer to a small bowl and whisk in remaining ingredients. Store on a tightly covered jar. Use as you would any seasoning.
