Though I have no idea what the healthiest food in the world is, I know what is the easiest to cook or prepare. The crown definitely belongs to sandwiches. You might think that it's not heathy due to its high calorie content, but if we take out the food you wrapped inside, what will leave? There are just two thin pieces of bread. So, if a sandwich is healthy or not really depends on what you put between these two pieces. As average people, we really need a kind of food which is both easy to cook and offers all the nutrition our body needs. When we keep our eyes on sandwiches, everything becomes easy. We just choose our favourite ingredients and squeeze them between two pieces of bread. You can even make a sandwich just like its creator while playing cards. Fortunately enough, your friends would even use your name for a new kind of food that originated from sandwiches.
