So, perhaps you recall my experiment with chili last year: I combined it with rice and ate it in a tortilla. This was a good combination as it lengthened out my chili and made it more digestible (a good trait for foods I eat). Tonight I decided to combine chili with spaghetti and tomato sauce (apparently chili spaghetti isn't that weird of a dish).
The spaghetti didn't stick to the chili+sauce as well as it does to the sauce alone, and the chili beans had this habit of falling off my spaghetti-laden fork, so I ended up eating them seperately most of the time (but when I got the right combination it tasted almost identical to the rice and chili). I think rice is a superior partner here, as it combines more evenly.
