Croque Monsieur

This is the French (and therefore superior) counterpart to grilled cheese sandwiches (although I do love grilled cheese sandwiches too).

(Not my photo, but can't find my camera so this'll have to do)

Toast bread lightly, and spread some butter onto one side

Grate swiss cheese (it's also really good to mix half swiss half dubliner)
Mix cheese with enough sour cream to make it stick (about two tbsp) and add salt and a good dose of pepper
Put cheese mixture onto non-buttered side of bread and add ham slices
Grill buttered-side down on low heat until cheese is completely melted.
Enjoy!
