Method
Step 1. In a small baking dish, gently toss to combine the potato, passata, tomato, capsicum and seasonings. Bake in a hot oven 200°C for 35-40 minutes or until potato is cooked.
Step 2. Meanwhile, cut a piece of baking paper 40 x 30cm and place on a baking tray. Top with the zucchini and extra capsicum and season. Place the fish on the vegetables, season, drizzle with oil and a little squeeze of lemon juice. Fold over the paper to enclose the fish and crimp together the edges to seal or tie with kitchen string. Bake in a hot oven 200°C for 15-20 minutes or until fish is cooked.
Step 3. Serve the fish with an extra squeeze of lemon juice and the potatoes alongside.
Tip: capsicum may be replaced with the same amount of fennel.
And, extra passata may be frozen for future use.
