We eat this quite often and its not expensive. Veggie sausages 10 in a pack were two for £3.00. I use about 8 for two of us and there is always some left over for lunch the next day. Then I get a carton of chilli chopped tomatoes with onion and basil. It is quite expensive at 59p but it says to use to cans and I just use the equivalent of one so its the same price as to value cans of tomatoes without chilli, onions and basil. I use more than enough pasta for two and this should cost lesds than 50p. Cheap and free on slimming world I believe. Dish up some salad and beetroot nom nom nom.
Doesnt it look nice:
