As I did say here comes the recipe for a lentil soup. Serves 3.
1 deciliter dry green lentils, soak as instructed on package (mine was soak 3 hrs in twice the amount water)
2 tomatoes
1 liter stock, homemade or from stock cube
1 big carrot or two small
1 piece of celeriac (about 0.5 deciliters when cut in small bits
Cut the tomatoes roughly, they are going to be well cooked anyways.
Cutting carrots and celeriac into pieces, size and shape as you see fit, I made sticks.
Put tomatoes and lentils in a casserole, and pour in the stock. Boil for 15 minutes.
Now add in the carrot and celeriac, simmer for another 15 minutes.
Taste and if needed add more salt.
