While they are good for a change in my opinion I still prefer to make my own 96% Lean Ground Sirloin patties. I get a 4 ounce one for 3 points based on total cal/fat/fiber. I still use the 1 point buns.
I buy Nature's Own hamburger and hotdogs buns at Walmart (1 pt each). I think they must be new because I have never seen them before. They are also made with whole wheat flour and not the usual white or enriched wheat flour most buns are made out of which was a big plus for me
Most of the supermarkets by me have their own store brand light bread, muffins and hamburger and hot dog rolls that are 1 pt. The plus side of the store brand is that the price is lower.
On the diabetic exchange system, they are counted as 1 Bread/Starch and 1 Protein. Legumes are not counted as vegetables because they have a high calorie count - around 110 per half cup cooked. They have a lot of fiber and are very nutritious.
