I did not have any chili's on hand, so I used many shakes from my crushed red pepper shaker. Maybe 1/2 tsp total? Anyway, it could have used more so be generous. Also, I used two 14oz cans of diced tomatoes, no extra salt and dried rosemary (although I would use fresh if available, it had a better flavor when I made it with the fresh last time). I cooked the beans a little longer than called for in the recipe so they did not have as much as a bite, undercooked beans don't agree with everyone in my family.
Anyway, this is the second time I made this dish and I can not get enough of it. I will need to try it with frozen green bean for winter time, but will probably add tomato paste to the sauce to compensate for the extra water from the frozen beans.
