This is a great soup because it uses very few and simple ingredients and is ready in a little more than twenty minutes. It can be kept in the refrigerator for about three days or it can be frozen. You can add spices of your choice or leave it pretty well as is. We leave it as is usually :) OR add a little crushed chili flakes to the pot while cooking OR stir in a little garam masala at the end.
1 small onion, chopped 5 oz (ca. 300 g) sweet potato, chopped (OK, that's about 1 small-medium, right?) 1 cup red lentils 3 cups veg stock (your own, preferably, or cheat)
In a large pot/saucepan, heat a little stock or water and add the onion and stir over medium for a couple of minutes until it is soft.
Add the sweet potato, lentils and stock, bring to a boil, reduce heat to simmer, cover and cook for about 20 minutes or until sweet potato is soft (the lentils only take about 15 - 20 minutes, so this timing depends on the sweet potato).
Blend in batches (either in a blender or using a stick blender/wand) until mixture is smooth, and return to the saucepan to reheat before serving.
You may find you need to add more stock or water - this can be VERY thick :)
It’s a great combo of flavours to which, as I say above, you can add your own for variety.
