You know what tastes cool? 

Semi-sweet (baking) chocolate and chicken nuggets. Not in the same bite, more like a couple bites of one, then a couple bites of the other. 

Also good: a moderately thick layer of deli/sandwich pepperoni on a hamburger. Better on leaner meat, best if you put the pepperoni on and then immediately eat it so the pepperoni is kinda cold and the rest is hot. This one I know about because my dad found a burger place in Japan that sold “Texas burgers”, which had pepperoni on them, and I decided to try one at home. Yum.
