One word....

CHILI.

I know it sounds strange, but my wifes homemade chilli cures all my after ride blues. Made with ground beef and beans (protein), mushrooms, onions, tomato sauce etc. with some cheese melted on top. Oh, and few Saltines for good measure.

Packed with that much protein, a big bowl of my wifes chili feeds my muscles and satisfies my appetite like very few other after ride meals I've had so far.
