This challenge is trying to teach you how dictionary unpacking (**) works. When you unpack a dictionary you get back a pair of key-value pairs corresponding to the keys and values in the dictionary. So a dictionary like this: {"name":"Tony", "food":"shawarma"} would result in this when unpacked: name = "Tony", food = "shawarma".

Now if you look at the unpacked dictionary and then at the code you have written you might notice a certain similarity. The unpacked dictionary produces the exact same values that you have manually typed into the format method. Because of that you can actually just replace that text with the unpacked dictionary.

Like this:

def favorite_food(dict):
    return "Hi, I'm {name} and I love to eat {food}!".format(**dict)

favorite_food({"name":"Tony", "food":"shawarma"})

Now whatever the value of name and food is in the dictionary will populate the name and food placeholders in the string you return.
