Evenly divide up the cheese and lasagna.
Sprinkle mozzarella cheese on a slice of toast and top with lasagna; sprinkle with cheese again and top with another slice of toast.
Continue to assemble the rest of the sandwiches.
Put pan on stove over medium heat until hot.
Butter the outside of each slice of toast and slide into the pan.

When bread is browned, flip and press down again; continue to cook for a few more seconds.
Remove from heat.
To assemble into "bites" and "sticks":
Let sandwiches cool down a bit.
Cut the crusts off a little wider (these will be your "lasagna sticks"), working the sandwich into a square shape.
Secure with cocktail forks or toothpicks.
