Grouping foods into Meals
I also lament this lack of functionality. I have been able to sort-of workout my meal planning by creating headers for meal groupings in custom foods and putting them in as a meal item.
I would be able to run reports on the best meals/worst meals by groupings but alas, I have been unable to figure out a better way to do this myself yet.
beef udon soup
Veges and dip
Tims Double Double
Hope this helps and perhaps motivates the developers to add this type of functionality.
