A thick vegetarian stew made of legumes and tons of vegetables served hot.
You can substitute a sweet potato if you want it to be healthier, but I find the starch from the Russet Potato helps fuse the flavors of all the vegetables.
I actually eat 2 portions myself for lunch, but I use a small potato if you are sharing use a very large potato.
Also, be careful not to let this burn. I have ruined more than one pot.
