...what kind of sandwich could you make right now? It must include four different ingredients.

I have corned beef, swiss cheese, sauerkraut and thousand island dressing. Four out of five ingredients for a reuben, and it's the most important four (no rye bread in the house, only sourdough, but that's good enough).

Assuming 'chili dog' counts as a sandwich (which it should ought to, dang it), I could make those, too. Hot dogs, canned chili, cheddar cheese and/or queso salsa, onions. (Sourdough bread in place of hot dog buns.)

If someone's being a hideous purist, last resort is sloppy joes. I've got the sloppy joe concoction, the onions, any number of different cheeses, and actual hamburger buns. Or if they want to get wild, I could make them a double-decker ice cream sandwich sandwich, with two ice cream sandwiches in the middle and ice cream sandwiches for bread. (And if anyone says those aren't four different ingredients, well joke's on them------------I've got regular, chocolate, mint chocolate chip and strawberry cheesecake.)
