This is a classic British snack inspired recipe - a mix between Welsh rarebit and cheese on toast - which is an open faced toast with a medley of melted cheese and dash of Worcestershire sauce. i add an egg into the cheese mix to help with setting of it, to add a bit of protein and to get that quiche-y type of topping! to this mix i also add a touch of mustard (English mustard is preferred!) for that little kick.
