The quantities of the ingredients outlined definitely would not feed 6 people. It fed 3 of us with a small portion left over. If I made it again I will double the veg and lentil quantities but keep the fluid the same amount.
When I made it this time I did double the spice quantities as we do like to taste the spices, also I boiled off the water for a long time as it was extremely watery and soupy (which is not what we wanted)
After making these slight adjustments it ended up super tasty and would make it again with changes.
