Last year in Lake Stevens elementary schools Langum held a Make a Rainbow at the Salad Bar promotion. Every student who purchased a meal was challenged to create a “rainbow” from the salad bar’s offering, by selecting items with at least three different colors. Students who were successful received a sticker. One school tested a rainbow coleslaw recipe made of green and purple cabbage, shredded carrots, red grapes, onions and oranges with a sweet vinaigrette. Fifth-grade students volunteered to pass out samples.
