The simplest dish that I know of is what southerners call indian cornbread. It is also called fried cornbread or hot water cornbread in some quarters.
Pour corn meal in a bowl.
Add some salt.
Pour in boiling water--paste should not be runny, but can stop just short of runny.
Shape into palm-sized disks with hands dipped in cool water.
Put in a cast iron skillet which has a thin layer of hot oil and fry until it starts to brown.
My mom and grandma cooked it. My wife's mom and grandma cooked it. Men cooked it in wartime, since all you need is corn meal, water, and oil--when they could get even those simple ingredients.
So few people cook anymore that I do not know if indian cornbread will survive.
