Begin by opening and draining the canned albacore tuna. Flake the tuna into smaller pieces in a large mixing bowl.

Finely dice the celery and red onion, adding them to the bowl with the tuna. Mix gently.

Add mayonnaise, dill relish, lemon juice, and yellow mustard to the bowl. Stir until well combined.

Sprinkle in dry dill, garlic powder, salt, and black pepper. Mix thoroughly and adjust seasoning if necessary.

Cover the bowl and refrigerate for at least 30 minutes to enhance flavors.

After chilling, stir the tuna salad and serve on bread, in a wrap, or over greens.
