Step 6
Serve immediately, garnished with extra parsley or a sprinkle of feta if desired.

Zusatztipps für die Zubereitung

When preparing the avocados, use a spoon to gently scoop out a small amount of the flesh to create a larger 'bowl' for the tuna mixture. Be sure to dice this extra avocado and fold it back into the salad to ensure none of that creamy goodness goes to waste. Using avocados that are perfectly ripe—yielding slightly to gentle pressure—will provide the best texture for this dish.

Varianten und Anpassungen

For a dairy-free option, you can easily omit the feta cheese or substitute it with your favorite vegan feta alternative. If you want to vary the protein, canned salmon or finely chopped grilled chicken make excellent substitutes for the tuna. You can also customize the vegetables based on what you have on hand, such as adding diced celery for extra crunch.

Serviervorschläge

These stuffed avocados are best served immediately with a side of mixed greens or whole-grain crackers for a more filling meal. To elevate the experience, pair this dish with a crisp Sauvignon Blanc or a light, chilled rosé. For an extra touch of flavor, garnish with a few extra sprigs of fresh parsley or a dash of black pepper right before serving.

Recipe FAQ Section

Can I make Mediterranean stuffed avocados ahead of time?

Prepare the tuna salad mixture up to 24 hours in advance and store it in an airtight container in the refrigerator. Wait to cut and fill the avocados until just before serving, as they will oxidize and turn brown once cut. If you need to prep further ahead, brush the avocado halves with lemon juice to slow browning.

What type of tuna works best for this dish?

Tuna packed in olive oil provides the best flavor and texture, as the oil adds richness to the salad. If using water-packed tuna, drain it well and consider adding an extra tablespoon of olive oil to the mixture. Solid white albacore offers a meatier texture, while chunk light tuna works perfectly fine and tends to be more budget-friendly.

How do I select perfectly ripe avocados?

Choose avocados that yield slightly to gentle pressure when squeezed in your palm. They should feel firm but not hard, with no mushy spots or dark indentations. If your avocados are underripe, let them sit at room temperature for 1-3 days. Once ripe, they can be refrigerated for 2-3 days to extend their shelf life.

Are there variations for different dietary needs?

This dish is naturally gluten-free and low-carb. For a dairy-free version, simply omit the feta cheese or use a vegan feta alternative. You can swap the tuna for canned salmon or chopped grilled chicken for a different protein source. Add sliced almonds or pine nuts for extra crunch and healthy fats.

What sides pair well with Mediterranean tuna stuffed avocados?

Serve alongside mixed greens with a light vinaigrette for a complete meal. Whole-grain crackers, toasted pita bread, or crusty bread help soak up the flavorful juices. For a heartier meal, add quinoa tabbouleh, roasted vegetables, or a simple Greek salad with cucumber and tomatoes.

How should I store leftovers?

Store any leftover tuna salad separately from the avocado halves in airtight containers in the refrigerator. The salad will keep for 2-3 days. Unfortunately, filled avocado halves don't store well as they brown quickly. If you have leftover avocado, store it in a container with a piece of onion to prevent browning, though it's best enjoyed fresh.
