2 tbsp. vegetable oil
1 med. onion, diced
3 cloves minced garlic
1 lb. ground beef or turkey
2 tbsp. chili powder
1/4 tsp. ground cinnamon
1/4 tsp. ground cloves
1 tsp. ground cumin
1/2 tsp. powdered mustard
1/2 tsp. ground nutmeg
1/2 tsp. paprika
2 tsp. salt
1 can diced or chopped tomatoes, with juice
2-3 cans black or kidney beans, undrained or partially drained (depending on how thick or thin you want it)
Sometimes I add a small can of tomato paste too if I want it more tomato-ey.
Of course, it's best the longer it cooks/sits.
I like the combo of spices -- it has a 'smoky' flavor. I also add red/green peppers. One of the great things about chili is that there's so much room for variation. HTH
