This was featured in the April 2012 issue of "Reader's Digest." I wanted to add it to Food.com so I wouldn't lose it! It is part of their Digest Diet feature. Here are the nutritional facts given in the article: (per 2-wedge serving): 341 calories, 17 g protein, 13 g fat (5 g saturated), 10 g fiber, 296 mg calcium, 10 mg vitamin C, 44 g carbohydrate, 603 mg sodium.
As mentioned in the printed article, you can substitute cottage cheese for the ricotta if you puree it in a food processor for a minute. Also, using pre-made whole wheat crust gives you a faster and healthy option.
