Its really hard to think of something that's doesn't look like diet food, what does your parents like? spag bowl with lean mince, chicken stir fry, steak with jacket potatoes, you can get lean steaks for yourself.
I think I'll stick to Fridays for wi? as we going be busy this Friday getting ready for Maisie's birthday, got family coming over for birthday tea on Saturday as well so want the house to look its best, going to do load of party food so it won't be healthy lol xx
