Cut the edges of the sandwich bread and cut into pieces as needed to cover the sides of the baking dish.
Mix the cream with the green onion and season with salt and pepper.
Spray a baking dish with cooking spray and cover with the sandwich bread previously dipped in the cream mixture without softening the bread, pressing it to take the shape of the baking dish.
Mix the tuna with the rest of the ingredients (except for the cheese and guacamole) and incorporate part into the bread, put another layer of soaked bread and tuna, and continue until finishing with soaked bread and place the cheese on top with small pieces of butter.
Refrigerate for at least 15 minutes covered with plastic wrap and then bake in a preheated oven for 20 minutes at 180ºC.
