Cooking the fillets and making a curry or a pasta dish or making oven chips with real potato will cost you the same or slightly more.
Sauce for curry/passata £1, 4 fillets £4, rice/pasta £1 that's 6 quid and you will get a couple of days out of that
Its being lazy, the cheapest shops are Lidil and Iceland, though they do way too much high calorie content food, though they have a massive range of sliming world foods well priced
