A short-cut for the slightly lazy... Heinz Wholegrain Minestrone Soup (in a 535g can) contains 4.5 serves of vegetables. Yes, it's mass-produced and no, it doesn't taste like home-made... but it does contain an absolute bucketload of legumes and vegies. One can for lunch, and you've got 90% of your RDI... Cheating? Perhaps. But on the days when the crisper is looking empty and 5 serves is looking doubtful, it can be a great escape-clause.
