So for rainbow week...my meta theme is Last Week, which has been super fun so far! I've got it stuck in my head that I really want to make a dish to represent every color for rainbow week, and I'm having a hard time finding something that fits into every color. I'd do a pic stitch and post all of the pictures together at the end of the week. I've got something that fits into the marinated meta for red (tuna poke), orange (orange/honey salmon), yellow (yellow chicken curry), green (tabbouleh salad), and indigo (pickled eggs), but I'm having trouble finding something that can be marinated that fits into blue and purple. I was thinking of making a blueberry cocktail and purple potato soup, but it doesn't fit :/

Does anyone have any suggestions? Or, do you think it would be cheating on my metatheme to just not make something marinated for blue and purple?
