It's never a good idea to solely eat ready meals as they do contain a fair amount of salt, however they are good to have if you're short of time. I'm busy most days and for days where I return home too late to cook I have a WW ready meal, but for the most part these days I cook my own stuff and freeze it so it's just a matter of taking it out of the freezer in the morning so I can heat it up when I get home. Much healthier and cheaper!
