Lemon Rice and Pea Soup

Lemon Rice and Pea Soup

This soup was born from leftover rice and a bag of frozen peas that needed using up, and it turned out to be one of the best budget soups in the rotation. At 45p a portion it is about as cheap as a proper meal gets. The lemon is the magic ingredient – it cuts through the simple stock and makes everything taste fresh and bright rather than heavy. Frozen peas are one of the best value vegetables in any supermarket at around £1.20 for a 900g bag, and they keep their sweetness better than fresh.

Total cost: £1.80 (£0.45 per portion) – Serves 4 people. Prep: 5 mins | Cook: 20 mins

Servings: 4 people
Course: Soup
Cuisine: Mediterranean

Ingredients
  

  • 150g cooked rice (leftover is fine)
  • 150g frozen peas
  • 1 onion, diced
  • 2 cloves garlic, minced
  • 1 lemon (zest and juice)
  • 1 litre vegetable stock
  • 1 tbsp olive oil
  • 1 tsp dried oregano
  • salt and black pepper
  • small bunch fresh parsley or dill

Method
 

  1. Heat the olive oil in a large saucepan. Add the onion and cook for 5 minutes until soft.
  2. Add the garlic and oregano, cook for 1 minute until fragrant.
  3. Pour in the vegetable stock and bring to a simmer. Add the frozen peas and cook for 5 minutes.
  4. Stir in the cooked rice and lemon zest. Heat through for 2-3 minutes.
  5. Remove from the heat and stir in the lemon juice and most of the chopped parsley. Season well with salt and black pepper.
  6. Serve in warm bowls, garnished with the remaining parsley and an extra twist of black pepper.

Tips and Variations

This works best with leftover cold rice – fresh hot rice will go mushy. No fresh herbs? A teaspoon of dried dill or parsley works. Add a tin of white beans for extra protein. This does not freeze well because the rice goes mushy on defrosting, so only make what you will eat in a day or two.
