My nana can't stop making this vintage dish from the 1950s! It's been so good!

1. In a large mixing bowl, combine the mayonnaise, sour cream, apple cider vinegar, and sugar. Stir until smooth and well combined.
2. Add the thawed peas, cheddar cheese, red onion, celery, and dill to the bowl.
3. Gently fold the ingredients together until the peas are evenly coated with the creamy dressing.
4. Season with salt and pepper to taste, adjusting as necessary.
5. Cover the bowl and refrigerate the salad for at least an hour before serving to allow the flavors to meld.
6. Serve chilled, and enjoy the taste of nostalgia.
Variations & Tips
For a bit of added crunch, you can mix in some chopped water chestnuts or sliced almonds. If you prefer a tangier flavor, try adding a tablespoon of Dijon mustard to the dressing. For a touch of sweetness, consider mixing in some diced apples or grapes. If you're looking to make it a bit heartier, you can add some cooked, crumbled bacon or diced ham. Remember, this salad is versatile, so feel free to adjust the ingredients to suit your taste.
