On a large rectangular platter, arrange the arugula in an even layer as shown.
For the "stars", arrange your diced red onion at the top left corner.
For the "stripes", top the arugula in alternating rows with cherry tomatoes and cheese cubes as shown.
In a small jar or bowl, add all the dressing ingredients and shake to emulsify.
Drizzle your dressing over the salad and serve.
Enjoy!
