Instructions

• Preheat oven to 450°F (230°C). Cut 4 large sheets of parchment paper 16 x 12 in (40 x 30 cm) each.
• Combine mayonnaise, parsley, Dijon mustard, honey, and turmeric in small bowl.
• Fold each parchment sheet in half, then open. Divide potato slices evenly among sheets. Season potatoes with ¼ teaspoon of salt and ⅛ teaspoon of black pepper.
• Add an equal amount of kale to each parcel, then place a piece of tuna on top. Season tuna with ¼ teaspoon of salt and black pepper. Brush tuna with mayonnaise mixture.
• Fold parchment over and tightly seal edges with small folds. Arrange packets on a baking sheet.
• Bake for 10 to 15 minutes until tuna is cooked through. Carefully open one packet to check done (take care with steam). Set packets aside to rest for 3 minutes.
• To serve, cut a cross in top of each packet and gently fold to open. Transfer to a plate or serve straight from parcel.
