Try to slice the bread very thin, it's ok if it's a little thick, your choice

Put plastic wrap on the table and the bread on top like in the photo

Put the béchamel sauce on top of the bread to make it soft and easy to roll it

Put a lair of ham all over the bread

Then slice the Brie cheese an put a lair too

After that a lair of manchego cheese

Cut it on a half and roll it up

Like this 😬 then take the plastic out and cut it in small pieces to bread it easily

Once is cut pass it down in egg and after that the bread crumbs

Like this

Dip fry them in hot hot hot oil until you get a nice golden-brown color

Like this, for the sauce boil the potatoes, then sauté them whit onion and tuna, blend it and ad the cream at the end, put salt and pepper

Serve it on a spoon, and put the sauce on top, enjoy it 😘
