I've never seen anything about the number of fat grams for lunch meat. It should be turkey breast or chicken breast with no added sugar (like honey-roasted). Read the labels for added sugar. The FAQ in the SB stickies is a good source of information for approved meats. I know it lists boiled ham and lean pastrami (maybe turkey pastrami) also.
I think it also lists lean roast beef. I bought some made by Healthy Choice at the deli counter of my grocery store. This was a roast that was sliced by the deli person. They also had Healthy Choice turkey breast.
