Finely chop/mince the garlic.
Place softened butter into a cup and add the garlic.
Use a knife to mix the garlic through the butter.
Butter six pieces of bread with the garlic butter.
Place three pieces of bread, butter side down, into your sandwich press (or if it only has room for two, do two of them now and then the other one after they're cooked).
Place two slices of cheese on each piece of bread in the sandwich press.
Place the other slices of bread, butter side up, on top of each one.
Close the sandwich press and cook for a few minutes until they have turned a light golden brown.
Be careful not to overcook as the garlic may burn.
Let them sit and cool for a few minutes before serving as the cheese inside will be piping hot.
