I am confused, I do not clearly understand what I need to do here, and I do not know how I can get it right, I need help

I am doing this challenge and I am not sure what I have to do. Can you help me?

string_factory.py 
def favorite_food(name=None, food=None):
    return "Hi, I'm {name} and I love to eat {food}!".format(name, food)
favorite_food(**{'name': 'Michelangelo', 'food': 'PIZZA'})

Hey, you need to rewrite the function, so that it fills in name with the value of the key name (and food) of the dictionary.

You have rewritten the function declaration, which you aren't allowed to do in the challenge. The function should accept a dictionary and your job is to pull out the values and insert them in the print statement using the format() function.

I do not understand... I can't get it to work. here's what I got

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

favorite_food(**{'name':'Rolph', 'food': 'Pizza'})

You shouldn't call the function, that often breaks the challenge. Delete the function call and try again.

So I need to do the challenge without calling the function? So I just needed to paste in what he already had written, I tried that, but that didn't work either. Sorry if the solution is obvious, cause I have no idea.

No, my bad I messed up. You need to insert the appropriate values in the format function, (value for key in dictionary)

I changed my code a little bit, and now I do not see what is wrong with it. Here's what I've got

def favorite_food(name=None, food=None):
    if name and food:
        return "Hi, I'm {name} and I love to eat {food}!".format(name, food)

favorite_food(**{'name':'Rolph', 'food': 'Pizza'})

YOURE NOT ALLOWED TO CHANGE THE FUNCTION PARAMETERS

here is what I've got now. 

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

favorite_food(**{'name':'Rolph', 'food': 'Pizza'})

What is wrong with this code?
