What's an unusual but excellent food combo you've tried?

Just ate a kimchi grilled cheese sandwich for breakfast, yum. With a dip of gochujang, mustard, soy sauce, kimchi brine.

There is a Mexican fruit salad with pineapple, mango, jicama, onion, and cotija sharp cheese, in an orange juice dressing, it is so good with onion, I would not have expected that.
