These little bowls are prefect for prep. I was cooking a shrimp pasta dish the other night and it called for making a cream sauce. I had to chop three vegetables, herbs, and have 2 different cheeses that went into the dish. Instead of having all of that cramped on my each end of my cutting board, I was able to have everything neatly placed out of my way in these little bowls. It was really convenient and I wondered how I cooked meals like this without them before. These bowls are awesome!
