Prepare the Base: Preheat the oven to 180°C (350°F).

In a bowl, mix the grated cheese, grated carrot, egg, and sour cream until well combined.

Coat a silicone baking mat with a thin layer of olive oil and spread the mixture evenly over the mat.

Bake the Base: Place in the preheated oven and bake for 15-20 minutes, or until the base is set and lightly golden.

Remove from the oven and allow it to cool for a few minutes.

Prepare the Filling: In a separate bowl, beat together the cream cheese and sour cream until smooth.

Stir in the chopped herbs, mixing well to combine.

Assemble the Roll: Carefully turn the baked base over and spread the filling evenly on top.

Gently roll it into a tight log, using the silicone mat to guide if needed.

Wrap the roll in cling film and refrigerate for at least 2 hours to set.

Slice and Serve: Once chilled, slice the roll into rounds and serve as a savory snack or appetizer.
