Slice the zucchini/courgettes into thin slices using a mandolin, food processor, or sharp knife.
Lay the zucchini slices in rows on a baking sheet lined with parchment paper.
Drizzle or spray the zucchini slices with a little olive oil and sprinkle with salt.
Grate cheddar or mozzarella cheese over the zucchini slices.
Bake the zucchini slices in a preheated oven at 180°C for 20-30 minutes until golden brown.
Allow the baked zucchini slices to cool, then flip them over so the cheesy side is facing down.
Top the zucchini slices with your desired filling, such as rocket, avocado, basil mayonnaise, and tuna, leaving space at the edges.
Carefully roll up the zucchini slices to create the rotolo (roll).
Enjoy the zucchini rotolo using parchment paper to avoid making a mess.
