You can even add your own recipes to MealPrepPro. This is ideal if you have a favorite go-to snack or breakfast up your sleeve. Simply tap the swap button beside the recipe you want to swap and choose the option "Your recipes" write your recipe name in here, add the nutritional information and you are ready to go. Each time you want to add this recipe to your plan this is where you'll find it.
Right now, it's not possible to add extra information such as steps and ingredients. This is a popular request and it's something we plan to add to MealPrepPro in future.
