How can I add my weekly standard meals that don't need a full recipe?
Add your standard weekly meals as a recipe on your CookBook, all you'd need to complete is the title and ingredients. You could create a tag to quickly access these meals, for example 'Weekly Simple Meals'. You could then add these meals to your planner.
Utilise the 'General Items' shopping list and add your ingredients here to copy to your weekly active list.
