Living in the UK - Missing US food. . ?

Awwwww! Poor you! Well, I would say try McDonald's or Burger King. Betty Crocker is quite common, so that shouldn't be too much of a problem. If there are certain things that you still can't get, I suppose you could try cooking more. We have lots of ingredients just hidden away in markets and back shelves. I'm sure you can still make your sweet potato and marshmellow cerole if that's what you like! LOL! I hope you're able to feel welcome here and that you don't feel too homesick! xxx
