Ingredients
For the Creamy Dressing

-
Dijon Mustard: 1 tablespoon
-
Lemon Juice: 1 tablespoon (freshly squeezed)

Dill Weed: 1 teaspoon dried dill (or 1 tablespoon fresh dill, finely chopped)

-
Fine Sea Salt: $\frac{1}{2}$ teaspoon (adjust to taste)
-
Black Pepper: $\frac{1}{4}$ teaspoon (freshly cracked)
For the Salad
-
Canned Tuna: 2 cans (5 to 6 oz each), drained well (solid white albacore or chunk light packed in water)
-
Sweet Green Peas: $1\frac{1}{2}$ cups (frozen peas, thawed and drained thoroughly)
-
Celery: 2 medium stalks, diced fine
-
Red Onion: $\frac{1}{4}$ cup, diced fine

-
Hard-Boiled Eggs (Optional): 2 large, peeled and chopped
Step-by-Step Instructions
1. Prep the Key Ingredients
-
Thaw the Peas: Place $1\frac{1}{2}$ cups of frozen sweet green peas into a colander. Rinse them briefly under lukewarm water for 30 seconds until thawed. Drain thoroughly and pat them dry with a paper towel to avoid watering down the salad dressing.
-
Drain the Tuna: Open two cans of tuna and press out as much water as possible using the lid or a fine-mesh strainer. Dry tuna ensures the dressing adheres properly.
-
Chop the Vegetables & Cheese: Dice 2 stalks of celery and $\frac{1}{4}$ cup of red onion into small, uniform pieces. If using hard-boiled eggs or block cheddar cheese, chop them into small bite-sized cubes.
2. Whisk the Creamy Dressing
-
In a small mixing bowl, combine $\frac{1}{2}$ cup mayonnaise, $\frac{1}{4}$ cup sour cream (or Greek yogurt), 1 tablespoon Dijon mustard, and 1 tablespoon fresh lemon juice.
-
Add 1 teaspoon dried dill, $\frac{1}{2}$ teaspoon garlic powder, $\frac{1}{2}$ teaspoon onion powder, $\frac{1}{2}$ teaspoon fine sea salt, and $\frac{1}{4}$ teaspoon cracked black pepper.
-
Whisk vigorously until the dressing is completely smooth, emulsified, and uniform in color.
3. Assemble and Toss
-
In a large mixing bowl, flake the drained tuna into medium-sized pieces using a fork. Avoid mashing it completely so the salad retains texture.
-
Add the thawed green peas, finely diced celery, diced red onion, cheddar cheese cubes, and chopped hard-boiled eggs (if using).
-
Pour the prepared creamy dressing over the tuna mixture.
-
Using a soft silicone spatula, gently fold the ingredients together from the bottom up until everything is evenly coated in dressing.
4. Chill and Serve
-
Cover the bowl tightly with plastic wrap or transfer to an airtight container.
-
Place in the refrigerator to chill for at least 30 minutes before serving. Chilling allows the flavors to meld together and firms up the dressing.
-
Give the salad a quick, light toss right before serving. Garnish with a sprinkle of extra dill or cracked black pepper if desired.
Chef’s Recipe Notes & Variations
-
Pea Selection: Frozen sweet green peas work best for this recipe because they retain a firm texture and vibrant color. Canned peas are generally too soft and will turn mushy when tossed with the heavy dressing.
-
Tuna Choice: Solid white albacore tuna yields larger, meatier chunks that hold up well in a cold salad. Chunk light tuna offers a milder taste and smaller flake size.
-
Low-Carb / Keto Adaptation: Omit the green peas or reduce them to $\frac{1}{2}$ cup to lower the net carb count, and use full-fat sour cream or extra-heavy mayonnaise in place of yogurt.
-
Storage Instructions: Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days. Freezing is not recommended, as mayonnaise-based dressings separate upon thawing and thawed vegetables lose their crispness.
Serving Suggestions
-
Classic Cold Side: Serve chilled in a bowl alongside summer picnics, barbecue chicken, or roasted meats.
-
Lettuce Boats: Scoop generous portions into romaine lettuce leaves, butter lettuce cups, or avocado halves for a low-carb, fresh presentation.
-
Tuna Pea Sandwich: Pile onto toasted sourdough, whole grain bread, or a warm croissant with crisp lettuce leaves.
-
Pasta Salad Mashup: Fold in 2 cups of cooked and cooled elbow macaroni or shell pasta to instantly turn this side dish into a main course tuna pasta salad.
