This is the Winning Recipe of the May 2012 Better Homes and Garden’s Prize Tested Recipe, created by Linda Cobb of San Diego, CA. She says: “It’s a flavorful way to combine summer vegetables with mashed potatoes. I’ve served it as a vegetarian main dish as well as a hearty side with grilled meats.”

  • 1/2 cup bottled roasted red sweet peppers
  • 1 8-oz. carton sour cream*

  • 2 medium zucchini, halved lenghtwise, sliced
  • 1 medium yellow summer squash, halved lengthwise and sliced

  • 1 medium sweet yellow pepper, chopped
  • 1 medium sweet green pepper, chopped
