In a large mixing bowl, combine the cooked ham, turkey breast, chicken breast, salami, and chorizo.
Add the cooked green beans, carrots, peas, pickled beets, olives, capers, pickled onions, and pickled jalapeños (if using). Mix gently to combine.
Stir in the chopped fresh parsley.
In a separate bowl, whisk together the mayonnaise, sour cream, Dijon mustard, red wine vinegar, and olive oil.
Season with salt and black pepper to taste.
Pour the dressing over the salad mixture. Gently toss to coat all ingredients with the dressing.
Cover and refrigerate for at least 2 hours to allow the flavors to meld.
Before serving, garnish with additional chopped fresh parsley, sliced radishes, and cherry tomatoes if desired.
Enjoy your meal!
