This salad is perfect with a grilled steak for a Tex-Mex meal, and most of it can even be prepared out in the backyard. Poblanos and cayenne make it pop. —Johnna Johnson, Scottsdale, Arizona

  • 1-1/2 pounds large red potatoes, quartered lengthwise
  • 3 tablespoons olive oil
  • 2 poblano peppers
  • 2 medium ears sweet corn, husks removed
  • 1/2 cup buttermilk
  • 1/2 cup sour cream
  • 1 tablespoon lime juice
  • 1 jalapeno pepper, seeded and minced
  • 1 tablespoon minced fresh cilantro
  • 1-1/2 teaspoons garlic salt
  • 1 teaspoon ground cumin
  • 1/4 to 1/2 teaspoon cayenne pepper
  • Lime wedges


  1. Place potatoes in a large saucepan; add water to cover. Bring to a boil. Reduce heat; cook, uncovered, 5 minutes. Drain potatoes and toss with oil.
  2. Grill poblanos, covered, over high heat 8-10 minutes or until skins are blistered and blackened on all sides, turning occasionally. Immediately place peppers in a small bowl; let stand, covered, 20 minutes. Reduce grill temperature to medium heat.
  3. Grill corn and potatoes, covered, over medium heat 12-15 minutes or until tender and lightly browned, turning occasionally. Cool slightly.
  4. Peel off and discard charred skin from poblanos; remove stems and seeds. Cut peppers into 1/2-in. pieces and place in a large bowl. Cut corn from cobs and cut potatoes into 3/4-in. pieces; add to peppers.
  5. In a small bowl, whisk buttermilk, sour cream and lime juice until blended; stir in jalapeno, cilantro and seasonings. Add to potato mixture, stirring in as much dressing as desired to coat. Serve with lime wedges. Refrigerate leftovers.
