How To Make Rainbow Roasted Vegetables

Making rainbow roasted vegetables is as easy as making any other type of roasted veggies.  Simply toss the vegetables in olive oil and bake in a pre-heated 425F oven for 25 minutes or until desired tenderness!  It’s just the presentation that turns the ordinary roasted vegetables into rainbow roasted vegetables.  Group together your veggies by their color and layer them into rainbow stripes! Here I got a stripe of purple onions, followed by a stripe of red bell peppers, then yellow squash, orange carrots, green broccoli and white cauliflower.  Those are the colors of my veggie rainbow, and you can certainly be creative with yours!  Feel free to use other colorful vegetables – sky is the limit!
