Sushi (which I haven't had before) was complex and vibrant. Each piece had its own array of flavors and I had two sauces to dip things in. Some parts were crunchy and some parts were chewy.
What was the real difference between the two meals? I would borrow an old expression and say one is eating for the stomach and the other for the mouth. The rice and beans tasted good, but my main reason for eating them was that I wanted to take nutrients and introduce them to my digestive system. Sushi filled me up, but I was more interested in the party my taste buds were having.
