Giant Jaffa Cake
I've seen this on a couple of forums so thought I'd give it a go- it's very simple to make, just make sure you don't eat the whole thing!
This one is 5 syns per slice if you cut it into 6 pieces.
Gnocchi with bacon, pesto and green beans
This meal is great for one of those nights when you pop into the supermarket desperately wanting a quick dinner without having something unhealthy! It's just a few items which you can quickly grab, and it takes under 10 minutes to cook! (Gnocchi will be with the fresh pasta, usually around the ready meals!)
I used the Tesco gnocchi which is 2 syns per 100g, and Tesco pesto which is 2.5 syns per tbsp.
