How to select range into a cell based on drop down selection

I have two sheets in my Google spreadsheet: Meal Plan and Recipes.

Meal Plan looks like this:

Recipes looks like this:

I would like to write a formula or function which allows me to select a meal from one of the 'Items' drop downs (in 'Meal Plan'!C2:C5) and have the 'Shopping List' field in that row populated with the 'Ingredients' values from the 'Recipes' sheet where the item selected matches the 'Meal' field in column A ('Recipes'!A2:A10).

Would this be a function or a formula?
