All you need to do is to put the ingredients into the pot and leave it on the stove. An easy and filling dish that can be made on an open cooktop.
This is an easy stewed dish that my busy mother used to make and is now a staple in my household. My mother's version only had bacon and potatoes, but I've added vegetables to make it tastier.
Beware of burning, since all you have to do is leave it on the stove.
