Roughly chop the onion and add to a large casserole dish with two tablespoons of the olive oil. Sauté gently for 5 minutes.

Finely chop the garlic and add to the pan, then roughly slice the mushrooms and add these too. Cook (without stirring) for 3-4 minutes, then add the stock cube, water and seasoning and cover. Simmer for ten minutes.

Meanwhile, put your oven on to the highest temperature. Cut the bread up into rough squares and toss with the remaining oil and some salt. Put in the oven and cook for 5-10 minutes until golden and crisp.

Whizz your soup with a blender or food processor. If it's too thin, add some more water to your liking, then add the Hendersons Relish. Check your seasoning and add more if necessary.

To serve, top each bowl with a handful of croutons and chopped chives. Yum!
