A home-made variant of Dutch snack "Vlammetje Tosti", which is basically a croque monsieur sandwich, except with spicy mincemeat instead of ham. You can buy these pre-packaged (or even prepackaged and frozen) in various of our supermarkets.
But they're pretty easy to just make yourself to whatever taste you like. Just fruit some minced garlic, minced onion and a bunch of spice powders you enjoy in a bit of oil. Add liquid spiciness of choice as well as whatever other liquids you like in there (I tend to toss in a little worcestershire sauce on top of the spice). Add the mincemeat in a thin layer.
Once browned all around & cooked through, toss in a little tomato paste to taste + a tiny bit of flour, then leave on heat for another minute or so.
Then it's just assembling your sandwich: slice of bread: bread, cheese, some of the mincemeat mixture, more cheese, other slice of bread, bit of oil or butter on the outsides, and toast with whatever's convenient for you--a frying pan, an oven, a toastie maker, etc.
