Can’t see that eggy crumpets have been mentioned… Whisk an egg or two in a large bowl, coat the crumpets in the egg, give em a squeeze so they absorb some of it, fry them on both sides… Delicious. Good with bacon, if bacon is acceptable to you. Wharburtons/fluffier varieties work better than most supermarket own brand ones, that tend to be a bit more solid.
Otherwise, standard butter/marmite/cheese combinations. And peanut butter.
Crumpets.
