I used to buy the Iceland ready meals in the late 90's when I was in college. Back then you'd get a 360g frozen curry for a pound.
Roll on another fifteen years and not only are the portion sizes a more generous 500g, but today I went in and they've slashed the price across the entire range to a more than reasonable 89p.
They mightn't be anything special but they're still tasty and fill a hole. There's a decent range of curries,pizzas, lasagnes, 'toad in the hole' etc available. Ideal for anyone on a budget wanting to get their freezer stocked up.
