Nice and hearty soup rich in protein that will both warm you up in a cold day and fill you for a long time.
Nice to haves:
Dried herbs mix
Pre-soak the lentils for couple of hours/ideally overnight
Put them to boil in water with salt for about 10min before adding peeled and chopped potatoes and if you have also finelly chopped onions for extra flavour.
Boil until the veggies are tender.
Right before finished, add cheese cut in small cubes or a spoon of dried milk for extra creaminess. You can also spicy it up with dried herbs.
