From My Test Kitchen...

For the first time since I started Atkins over two years ago, I made chili.      I've been avoiding most beans all that time because of the carb level, but last year I discovered edamame (soy beans in the pod), and that I liked them.      When shelled, they resemble more vividly-green lima beans but taste less mushy/pasty.    Last week I found frozen edamame in the kosher market ("Dr. Praeger's" brand).   The price was more than I like to pay for beans, but since I wanted to try the chili with a bean I already liked, I gritted my teeth and paid for them.    

The chili looks a bit odd with green beans instead of red or black ones, but it tastes like chili, and the beans only have 4 "net" carbs per serving.   (I think the tomatoes have about five and the seasoning mix adds one or two).
Next step is to look for canned soybeans and see if the carb count remains low.
