When you are fed up with festive food and the cupboard is almost bare, try this soup recipe.
Peel and chop the onion.
Scrub & chop the potato and carrot
Cover with water, add salt and pepper if you want, bring to the boil, simmer until cooked.
Mash it all together or blend with a stick blender.
This is one of my favourite soup recipes, it cost less than £1 for 4 servings.
