Prep all produce separating by fruit or vegetable and color. You can do this all at once or one at a time.
If not being consumed right away, cut fruits will need to be rinsed with diluted lime juice to prevent browning.
Progressing one color at a time, add vegetables shaping like a stripe and then the fruits of the same color bowing downward. See picture. Stack them as high as you can. Red vegetables go first, then red fruits. The following colors are orange, yellow, green, and blue/purple (combined).
Mix Greek yogurt and Onion dip mix in a small bowl. Add to one of the small white serving dishes.
Dice white cheddar cheese and put in a small white bowl.
Place the cashews and crackers in their own small bowls.
Place the wheel of brie in a white bowl. Heat in the microwave in 30 second increments until desired consistency and stir when ready to serve.
Arrange the white bowls together as to look like a "cloud" at the end of the rainbow.
Cover until time to serve. Serve with a cheese knife for the brie. Enjoy!
