If you have access to a heating element, you can make tamale polenta gruel! I use nixtamalized cornmeal, copious amounts of camping oil, nutritional yeast and whatever spice blend I packed. You can also add walnuts or sunflower seeds. It is hot, filling and tastes like gods love. I vividly remember crying for joy eating my first bite on a bike tour. I had got the cornmeal from a hippie store at like 85 cents a pound and was profoundly sick of my other camping food.
