Rosie - on some of my recipes, I was able to get the "vitals" and on some, I basically revamped "old" recipes into healthier ones, and being that I'm not a dietician, I didn't post "vitals". I think you can look at the ingredients and compare them to a meal. For instance if the recipe is for a soup and it has 1 pound of chicken, several veggies, and pasta or rice, and it serves 4 - then I would count a serving as 4 oz protein, 2 veggies (depending on how many are in the recipe) and a starch.
I hope that helps?
