The portions vary by recipe. While the smoothies are intended to be just for one, some of the omelet recipes will make two. Many of the Lunch and Dinner Recipes are the same way.
The best way to tell is in the preparation - for example if it says something about cooking half for one and the other half for another the chances are that the portions are two for that recipe.
