-Shepherd's pie normally has a layer of mashed potato on top. But, cooking the potato and mashing it as an extra step. I think it is easier to mix up a topping of polenta, flour, soy milk and egg. This topping has the added benefit of soy milk which is a legume. It also has a lower GI (glycaemic index) than mashed potato.
-Canned and frozen fruits and vegetables are usually just as nutritious as fresh fruit and vegetables. They are preserved as soon as they are picked and will retain more nutrients than fresh vegetables or fruit that have been stored in fridge for over a week.
-Try adding a handful (or more) of chopped edible "weeds" such as sow thistle, mallow, amaranth, stinging nettle,nightshade or sea celery (if you are near the coast). See my edible weeds page.
-Mince meat dishes are a great opportunity to “disguise” vegetables, if you need to, so that children and some adults will eat them.
