Yes, I ordered that bread the last time too and it was very good. For chili I ordered the Walden Farms Marinara Sauce that had 0 net carbs. The first time I made chili I can't remember if I used the PC Blue Menu diced tomatoes, or the Hunt's No Salt added Tomato sauce. They were quite high in carbs, but less than any other tomato sauce I found. The lowest pasta sauce from a store at home I found was Classico (not sure what you put in your chili). With the canned black soy beans, it worked well to make the chili in the crock pot so they cooked all day and softened up. Good luck with your chili.
Let me know what spices you use. I used to always used the French's or Club House packages of chili spices but they are very high in carbs. I haven't yet found the right mixture of spices and would love some suggestions.
