All you need to do, is to tell the format function where to get the value for the name and food. If you unpack dict (**dict), in the format function. then it will look for the value of 'name' and 'food' in the dict that was passed in.

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

This code passed the challenge, I hope this will help you :D

Remember this: a dictionary is assigned to a variable name, and the dictionary itself is made with keyword/value-pairs. Like so: 

    my_dictionary = {'keyword': 'value'}

if you print my_dictionary you get the dictionary as a whole:

    print(my_dictionary)
    >>> {'keyword': 'value'}

If you wan't to access only the value you need to give the dictionary the keyword for the value you wan't: 

    print(my_dictionary['keyword'])
    >>> value

Also, you have a function unpack that you haven't defines.

Hope that helps you to complete the challenge.
