# Swap Meals

Use the `swapMealPlanRecipe` mutation to replace a recipe in an existing [Meal Plan](https://docs.suggestic.com/graphql/query/queries/meal-plan/meal-plan-1).  

Replace a single recipe on a specific day and meal by using the `mealId` argument or replace all recipes for every day of the meal plan for a specific meal by using the `mealTag` argument.
