I'm not sure if I'm completely in compliance, but I found these awesome little 100% whole grain round breads. They're very thin, almost like a pita, but they are delicious and perfect for a quick sandwich. They should be just fine for Ph2.
Oh, they're called "Earth Grains Thin Buns" with only 100 calories, no high fructose corn syrup, and they come in 100% whole wheat or whole grain. I found 'em at my grocery store over next to the hamburger buns. Yummy!
