Step-by-Step Instructions

Step 1: Prepare the Base
Drain the canned tuna thoroughly to avoid a watery salad. Use a fork to flake it into smaller pieces and place in a large mixing bowl.
Step 2: Mash the Avocado
Cut the avocado in half, remove the pit, and scoop the flesh into the bowl with the tuna. Use a fork to mash the avocado slightly — leave it a bit chunky for better texture.
Step 3: Add the Vegetables
Stir in the finely chopped red onion and celery. If using any optional vegetables like diced cucumber or tomatoes, add them now.
Step 4: Season and Brighten
Drizzle in the lemon juice and sprinkle with salt and freshly ground black pepper. Mix gently until all ingredients are combined and coated evenly.
Step 5: Garnish and Serve
Stir in chopped parsley if using. Taste and adjust seasoning. Serve immediately or refrigerate for up to 24 hours for best texture and flavor.
