What great ideas. Prep bowls were given to me this summer as a gift by the person that recruited me as I do a lot of prep work for my weekend cooking and also serve stuff as "make your own salads" where every ingredient is in its own bowl and this way it stays nice and moist if I have leftovers. Lettuce is of course in a large pretty bowl but tomatoes, carrots, peppers, scallions, cucumber are all diced and put in their own bowl.
