Your shopping list is auto-generated, and each item comes from the ingredients list of a recipe. If you add a meal to your plan from the recommendations, you can't edit your shopping list as this may affect the calorie, macronutrients, and allergen info of your meal. However, you are allowed to edit the shopping list item on your original recipes. In this case, just tap the Edit button on top of the meal detail page. This will start the chat with Jo and it will allow you to edit your shopping list.
