Sausages and mash were one of my favourite foods as a child, and my niece and nephew love it too. Pork sausages and a few potatoes come cheap, so it's a cost-friendly meal too. There are a few drawbacks however; it's not the healthiest meal out there, and I'd rather give my niece and nephew the best I can afford.
Instead, I've swapped pork for beef sausages (less fat), and substitutes potatoes for vegetarian mash and added a couple of eggs for extra lean protein, which growing kids need. Safe to say both my niece and nephew wolfed this down, and even though there was still some food left over on my nieces plate, she wasn't hungry and she'd been fed - all I need for peace of mind.
