Thaw peas fully and pat them dry with paper towels to remove excess moisture. Dice cheddar cheese into 1/4-inch cubes. Finely chop celery, red bell pepper, and red onion, aiming for uniform sizes for even texture.

In a large bowl, gently combine peas, cheddar cheese, chopped celery, diced red bell pepper, and minced red onion. Toss together, taking care not to crush the peas.

In a separate small bowl, whisk together mayonnaise, sour cream, apple cider vinegar, sugar, salt, and black pepper until smooth and creamy. Taste and adjust seasoning as desired.

Pour dressing over pea mixture. Gently fold until all components are evenly coated. Cover and refrigerate for at least 1 hour, preferably 2, to allow the flavors to meld.

Before serving, stir salad gently to redistribute dressing and check seasoning. Optionally, garnish with reserved cheese for visual appeal. Serve chilled.
