Gather the ingredients so that you have everything close at hand on the counter or table.
Prepare the Ingredients
In a medium saucepan, cook 1 1/2 cups dried macaroni or small shells according to package directions. Drain and set aside to cool to room temperature.
While pasta is cooking, in a large skillet, cook 5 slices bacon until browned. When cooled, crumble into small pieces.
Defrost 1/2 cup frozen peas in microwave for 2-3 minutes. Using a handheld grater, coarsely grate peeled carrots to make 1/2 cup shredded carrots.
Make the Salad
In a large bowl, combine 1/2 cup real mayonnaise, 1/4 cup sour cream, 2 tablespoons half-and-half, and 1 tablespoon ranch seasoning mix, 1 teaspoon dried minced onion, and 1/4 teaspoon garlic powder. Whisk until smooth.
Stir in crumbled bacon, thawed peas, shredded carrots and 2 tablespoons diced pimentos. Slowly add the cooled macaroni and stir until combined.
Cover and refrigerate until ready to serve. Stir before serving. Serves 4-6.
