How to cook
The sheets are immersed in boiling water for 2 minutes. Make a béchamel sauce from the butter, flour and milk.
Add a few pieces of processed cheese to it. Make a mixture of the diced smoked fillet, grated cheese and add the corn. In a tray, arrange a layer of lasagna sheets, then filling and pour on sauce. Alternate until the products run out, ending with a layer of lasagna sheets.
Top thoroughly with the rest of the béchamel. Bake the lasagna at 392°F (200 °C) and right before it's ready, grate plenty of cheese on top.
Bake again until golden.
