Let me tell you something about peanut butter; anything- ANYTHING savory goes with peanut butter. One of my favorites is tuna casserole with a pb sammich and some milk. The only time I don't have it is when I put the tuna directly on the bread, in which case it's buttered.

I'll also do ramen on mashed potatoes if I'm feeling starchy. Mustard is something I'll put on just about anything; ramen, steak, liver puree, I put it on a corn cob once. And one of my most recent discoveries! Hummus spread on toast and topped with chicken salad.
