If you're looking for a vegetarian option, use both a tin of black beans and a tin of kidney beans in place of the meat. Chopped green peppers are also a great addition for a vegetarian version.
Some other great toppings to try are a dollop of soured cream and a few sliced jalapenos to spice it up!
Something else. Not four tablespoons chilli but 4 teaspoons chilli. This is what I changed. I also served it with corn chips and a very cold tossed salad on the side. - 22 Mar 2011 (Review from Allrecipes AU | NZ)
This was excellent although someone should change the 4 tablespoons chilli to 4 teaspoons of chilli in the ingredients list. I used 4 teaspoons and although quite hot was very very tasty. - 22 Mar 2011 (Review from Allrecipes AU | NZ)
