Lentil barley soup

Ingredients
1 tablespoon of olive oil
*1 small onion (finely diced)
*2 cloves of garlic (finely diced)
a handful of button mushrooms (quartered)
1 teaspoon of ground cumin
1 teaspoon of ground coriander
1 teaspoon of garam masala
1/2 teaspoon of tumeric
3 carrots (diced)
1/2 celery (diced)
3 zucchinis (diced)
2/3 cup of red lentils
1/2 cup pearled barley
the juice of two fresh lemons
water (or *vegetable stock if you can eat it)
salt & pepper to taste

[*Obviously I didn't add these, but I think that it would have been even yummier if I had.]

Heat the olive oil in a heavy-based pot over a medium heat for a few minutes. Add the onion (if you are lucky enough to be able to eat it) and fry for about 5 minutes (until it becomes translucent). Add the garlic and spices and stir thoroughly. Add the mushroom and stir so that it becomes coated in the spices (if you cannot eat onion - like me - then cook the mushroom first and then add the spices to it).

Once the mushroom has browned slightly, add the other vegetables and stir together. Leave the vegetables to sweat over the heat for about five minutes.

Add the lentils and barley and stir through. Then add about a cup of water (or vegetable stock) and stir for a couple of minutes. Add the lemon juice and more water (the amount can vary depending on how liquidy you would like your soup to be). Raise the heat in order to bring to a boil, and then cover and let it simmer over a medium-low heat for about 20 minutes.

It is ready when the lentils are mushy and the barley is soft to chew. Add salt & pepper to taste and serve with some yummy crusty bread.
