Weeklies are there to be used hun, don't worry about it! xx Just make sure you take the time to enjoy your TV snacks instead of eating them mindlessly and then realising you didn't even taste them! Enjoy your walk tomorrow and good luck for your WI, I'm sure you'll be fine!
Some low-point snack ideas:
Yoghurt/frozen yoghurt
Fruit (frozen makes it last longer!)/tinned fruit rinsed
Quark mousse/cheesecake (very healthy and extremely filling!)
Stewed fruit (rhubarb/apple etc) with sweetener/cinnamon (yum!)
Veg (carrots/celery/cucumber/tomatoes etc) with low-fat dip/houmous/cottage cheese with ryvita/low-fat crackers perhaps?
Butternut squash chips (can be made sweet or savoury)
Choc: Freddos, Curlywurly's, Smarties, Milkyway Crispy Rolls, Mini Milkybar, Fudge, anything 'treatsize' are all only 3pp each
Adding a little bit of ice cream to a fruit salad etc is always nice for a telly treat
Otherwise, Twix/Wispa/Caramac/Mars etc ice cream bars are only 3pp, they tend to last longer than a Kitkat too but I am a huuuuge ice cream fan
Twisters are only 2pp!
Extra-light babybel's are only 1pp each
'cake bars' usually aren't too bad pointwise either compared to actual chocolate bars, most are only 3-4 whereas their choc equivalents are 7-8pp each
Sugar-free jelly is free and usually keeps you from wanting something else to snack on for a while! Sugar free jelly with berries inside is delicious
