What are some VERY simple things to cook on a stove?

spegetti, stir fry, omellete, french toast, noodles, soup, grilled cheese, fried bologna sandwich, hamburgers, hotdogs, u can buy stuff to make sushi, i do it all the time, just get the seaweed(nori), sticky rice, and something to put in the middle( anything form tuna, shrimp, sasuage, anything u want really)
