Let’s keep this real simple: purple cabbage linguine (one of my favorite monochromatic easy meals, from Color Me Vegan), plus some slices of roasted ‘carnival’ squash, which as a nice yellow flesh and edible skin.
I s’pose I could’ve arranged the plate so it was rah-rah my alma mater, University of Washington, whose colors are purple and gold, but as much as I enjoyed my time there, I have no such color-centric loyalties.
