i'm with expatty: ya gotta have the onions and sour cream!
i also like to use cubed lamb (not ground) in my chilli. it gives it a more meaty flavor, imo.
larry, since you're a vegetarian, i guess you don't need meat suggestions. but, how about adding a diced fennel bulb to substitute for some or all of the onion, or fennel stalks for some/all of the celery?
i love fennel. it's another one of those background flavor dealios.
The way that you wander is the way that you choose. The day that you tarry is the day that you lose.
Sunshine or thunder, a man will always wonder where the fair wind blows.
