Tinned food isn't always bad... you can do some decent stuff with it... and this is the perfect example. If you're camping and can't keep things refrigerated then make the most of a couple of tins to knock up an awesome breakfast.
Heat a frying pan up over a fire or gas stove and splash in a couple of tablespoons of oil. Peel an onion and grate it into the pan, then cook for 5-10 minutes until softened.
Open the tin of new potatoes and drain them, then cut the larger ones in half. Open the corned beef too. Add the potatoes to the cooked onion to sauté and go golden. Rip up some fresh thyme into the pan and season with a pinch of salt and pepper.
Crumble in some corned beef and heat it through over the fire or stove as you toss everything together. Make a few wells in the potato mixture and crack an egg into each. Continue to cook for 4-5 minutes, adding a lid on top to trap in steam, until the whites are set but the yolk is still just runny.
Tuck into the hash and why not serve them with a tin of baked beans... easily heated up in the fire, in their tin (just remember to take the lid off and stir occasionally).
