To Make in an Instant pot: Use the saute function: fry onions & chard stocks until the onions are golden. Add the lentils, potatoes and 3 1/2 cups of stock. Turn off Saute mode. Cover and steal the pressure cooker. Set for 15 mintes on bean/chilli mode. Once finished do a quick release and follow step 4 to 7 in the original recipe.
