Vesta meals were, at one time, manufactured by the Bachelor's factory in Sheffield.
Looking at the packet of Vesta Paella in my kitchen cupboard reveals that 'Vesta' is a registered trade mark of H L Foods Limited but the products are currently produced by Premier Grocery Products Limited (of Long Sutton in Lincolnshire).
As others have mentioned, Vesta meals are still available in some of the big supermarkets but they also appear quite often in '99p' or '�1' shops. I buy them as special treats for the days when I can't be bothered to cook anything. (Yes, I know that they've been regarded as 'naff' for several decades. Yes, I know that they contain MSG. Yes, I know that they offer very little in terms of nutrition. Yes, I know how to cook the 'real' versions. But I still love all Vesta meals, especially the Beef Risotto).
