Lentil and Vegetable Potage in the Slow Cooker

I love making home made soup, its so comforting and ideal for a weekend lunch or for packing and taking to work. This recipe is so simple and so delicious and is so healthy too, what ever your diet this soup is for you. Potage was a medieval staple and even though I have taken some "poetic" license in including ingredients that were not available at that time, such as potatoes, onions, etc,  I think its can still be called a potage.
Lentils are used to give a smooth rib sticking velvety feel to the soup supplemented with seasonal local vegetables. I slow cooked this soup  in my slow cooker but this is not absolutely necessary and you would get the same great results on the hob.What you need

• 1 cup red/orange lentils
• 1 large onion, peeled and  chopped 
• 1 large carrot, peeled and chopped
• 2 sticks of celery, chopped
• 1 large potato, peeled and chopped
• A little oil / butter
• 2 cloves of garlic
• 2 bay leaves
• Sprig of fresh rosemary
• Small piece of pared lemon rind 
• About 1 liter vegetable stock - this needs to be hot / boiling
• Salt and Pepper

What you do

• Switch on your slow cooker to pre heat
• Heat a little oil or butter in a large pan and add the vegetables, cook for a few minutes until slightly softened
• Place the vegetables along with the lentils, stock, herbs and lemon rind in the slow cooker
• Cook on high for about 2 - 3 hours, until the vegetables are soft and the lentils mushy
• Remove the bay leaves, rosemary and lemon rind
• Process to a smooth velvety texture with a hand held blender, taste and season as appropriate, you may also want to add a little hot water or stock to thin the soup to your desired consistency.
