Step‑by‑Step Instructions for Tuna Stuffed Avocados
Step 1: Prepare the Tuna Salad
In a mixing bowl, combine one can of high-quality albacore tuna with about three tablespoons of mayonnaise, two tablespoons of finely diced celery, and two tablespoons of diced red onion. Add in one tablespoon of Dijon mustard, a pinch of salt, and a sprinkle of pepper. Mix everything together thoroughly until you achieve a creamy, cohesive tuna salad, which should take around 2-3 minutes.
Step 2: Halve the Avocados
Take two ripe avocados and slice them in half lengthwise. Carefully twist to separate the halves and remove the pit gently using a spoon or your fingers. The avocados should be slightly soft to the touch, indicating they are ripe and perfect for this recipe. Place the avocado halves on a serving plate, cut side up, and prepare them for stuffing.
Step 3: Stuff the Avocados
Using a spoon, generously fill each avocado half with the prepared tuna salad, ensuring even distribution across each half. Aim for a nice mound of filling, allowing it to overfill slightly for an appealing presentation. The creamy texture of the tuna salad will contrast beautifully with the buttery avocado, creating a delightful visual.
Step 4: Serve or Store

If you’re not ready to serve them right away, it’s best to store the tuna salad and avocado halves separately in airtight containers to maintain freshness.
