Store the Lentil Strudel in the fridge for up to 3 days, or alternatively, you can freeze it.

You can prepare the lentil filling up to 3 days in advance, storing it in an airtight container in the refrigerator, and then use it to make the strudel.

You can use whole wheat puff pastry or gluten-free. Additionally, instead of puff pastry, you can use shortcrust pastry even homemade.

To accompany the strudel, you can prepare a simple tomato sauce.

You can replace the fontina with your preferred cheese, or omit it for a lactose-free version of the strudel.

To make the lentils more digestible, rinse them and soak them in cold water for up to 2 hours.
