The best, easiest chili to make that I've found is using Clark's Gringo Chili Mix

I order about 20 packets per year since I moved from Texas (can't get real chili in NY!!!)

I also hear their salsa mix is really good..but I'm not a fan of salsa. If you do try it, I HIGHLY recomend trying it with Julio's chips
WARNING - watch your eyes on the Julio's chips site. :P
