Can't help you with UK sites, but have you tried the recipes from this website? I have tried two myself and must say they are fantastic.
Beef and Bowties noodles - this one calls for sundried tomatoes but I really don't care for them so I left it out. Otherwise all other ingredients seem to be standard.
Chicken with Pierogies - this one is also fantastic. I think it has standard ingredients too.
Hope this helps you.
