I think there are many ways to eat healthily without resorting to ready meals. I detest cooking, particularly all the faffing about chopping and assembling ingredients. I’m a great fan of Jamie’s and Ainsley’s five ingredients books, which both have lovely recipes which take minimum effort.
One range of ready meals I do like though is the Authentic brand. They only do curries, chilli con carne and faggots I think, but their curries are excellent. It’s far too much faff to make a curry yourself, which won’t taste as good, although the vegetable one in one of the 5 ingredients books is nice.
