While a good pizza is the timeless go-to standard, probably my favorite meal of all would be my grandfather's pork chops and pork chop gravy--the man never followed a recipe, and thus never left one, so now that he's no longer among the living, his infrequent deific cuisine is now joined with the annals of history and legend. It was a transcendent pleasure that I'll never again experience. Dammit.
As for drink, that's too easy: Mountain Dew. I'll drink it until it kills me, which may not take very long, but who wants to live forever, anyway? But if you must coerce a classier answer out of me, I'm quite fond of my grandma's strawberry lemonade. Now, SHE'S still around, so I don't get to miss out on that, too. So, suck it, life!
