I have come up with a few recipes and basically I follow the lean and green guidelines. I try to only use the veggies listed and the lean portion sizes, then I determine how many servings of each thing I have used and divide the portions appropriately for each Lean and Green serving.
As an example, if I have 4 different servings of protein (like eggs, lowfat cheese and chicken) I try to make sure that there are 4 servings of veggies in the meal as well. Then I just divide it into 4 servings.
If you are following the Lean and Green guidelines, carbs, calories, fat and other issues aren't issues. (as long as you are staying within the guidelines).
In adapting recipes, I just go through the recipe and see how I can apply the Lean and Green guidelines to the recipe and work it in. A good example is the zucchini pie recipe I listed. My original recipe for that included flattening out a can of Pillsbury crescent rolls in the bottom of the pan. I just deleted that and increased the veggies to make sure there were enough veggie portions for the lean and green.
Hope this helps.
