Top two toaster waffles with some shredded cheese, then a handful of ham (and optional turkey) and then more cheese. Slather the other two toaster waffles with raspberry jam and use as a top to the cheese topped waffles.
Bring a frying pan to medium heat and melt 1 tablespoon of the butter in it.
Whisk the eggs and milk together in a shallow bowl.
Dredge one sandwich in the egg batter then place in the frying pan. Top with a cover and cook until the sandwich is browned, flip and cook the other side until the cheese is melted. Repeat the process with the additional butter and other sandwich and serve immediately.
