storage/reheating

To store:

Refrigerate the prepared filling (separately from the avocado halves) in an airtight container for up to 2 days.

FAQs

Can I make tuna-stuffed avocados ahead of time?

Yes, you can prepare the filling ahead and store it separately. Assemble just before serving to prevent browning.

What type of tuna is best for this recipe?

Tuna packed in olive oil offers richer flavor and texture, but water-packed tuna can also be used for a lighter option.

How do I prevent the avocados from browning?

Brush the exposed avocado with lime or lemon juice and wrap tightly with plastic.

Can I use canned salmon instead of tuna?

Absolutely. Canned salmon is a great substitute with a slightly different flavor.

Is this dish suitable for keto diets?

Yes, it is low in carbs and high in healthy fats and protein, making it ideal for keto.

What if my avocados are too firm?

Allow them to ripen at room temperature for a day or two. They should yield slightly to pressure when ripe.

Can I add mayonnaise or yogurt to the filling?

Yes, adding a spoonful of mayo or Greek yogurt can make the filling even creamier.

Is this recipe child-friendly?

Yes, but you may want to omit the red onion or walnuts for picky eaters.

How do I serve this for a party?

Serve smaller scoops of the filling in mini avocado slices or use it as a dip with crackers.

Can I freeze the tuna mixture?

Freezing is not recommended due to the texture change in avocado and feta upon thawing.
