I pretty much live off of peanut butter. I eat it nearly every day, often a few times a day. It is simply one of the tastiest foods that has ever existed. And if you buy a good high quality peanut butter, it is also pretty nutritious. It is high in protein, Vitamin E, magnesium, iron, selenium and Vitamin B6.
