I have a list of python dictionaries that look like this:

sandwiches = [
    {'bread':'wheat', 'topping':'tomatoes', 'meat':'bacon'},
    {'bread':'white', 'topping':'peanut butter', 'meat':'bacon'},
    {'bread':'sourdough', 'topping':'cheese', 'meat':'bacon'}
]

I want to pass this as a POST parameter to another Django app. What does the client app need to do to iterate through the list?

I want to do something like:

for sandwich in request.POST['sandwiches']:
    print "%s on %s with %s is yummy!" % (sandwich['meat'], sandwich['bread'], sandwich['topping'])

But I don't seem to have a list of dicts when my data arrives at my client app.
