Hi hope you had a good time. I recommend veg. Whatever you like now and then try branching out into other thing you haven't tried. Obviously its not an unexpected recommendation for people trying to be healthy/loose weight, but its true. Can be fresh, tinned (in water) or frozen it makes great 0PP soups to fill you up and can really bulk out meals if you suddenly realise what "correct portion sizes" are and it comes as a shock.
If you aren't already aware of this trick, a tin of tomatoes bulks out anything from bolognaise soup to pasta sauce and is generally 0PP. They were my lifesaver before WW and even moreso afterwards. Also lovely drained on toast or thins.
Others include Warburtons sandwich thins (3PP) much less than a regular sandwich but still hits that "bread" spot when you need it.
Eggs, high in protein and filling, they're great for breakfast or hardboiled as a snack, I even do them in the microwave at work like a student.
Have you tried any of the "alternatives" to pasta such as Quinoa or Bulgur Wheat? Both have slightly low PP than white pasta and are yummy.
Definitely stock up on marinades and low PP flavours so you don't get bored. Soy, Oyster, balsamic, teriyaki and others are all 0 or 1PP in limited quantities.
