These halved dried peas can be deep green or golden-yellow. I think the green ones are superior in flavour, but both are suitable for thick, warming pea soups, or for purées or cutlets.
Although they are cheap, split peas are actually brilliant on the nutritious front and provide plenty of fibre in the diet. This soup is just one way of enjoying them...
Vegetarians certainly won't feel short-changed with this sumptuous meat-free version of shepherd's pie: in fact, meat eaters will no doubt love it as much as they do!
