Step 1

Slice the red onion very thinly and salt generously and let stand 15 minutes until it begins to release its liquid (this will remove the bitterness). Rinse well, squeeze dry.

Step 2

Place fish, garlic, onion, salt, pepper, fresh chilies, and lime juice in a shallow serving bowl, gently mix, and marinate in the refrigerator for at least 30 minutes before serving. The longer you marinate the firmer and more “cooked” the fish will become.

Step 3

Before serving, gently toss in the fresh cilantro, cucumber and tomato and a drizzle of olive oil, gently mix.

Step 4

Taste for salt and add more if necessary. If adding avocado, gently fold it in at the end, after everything is mixed, making sure to use one that is not too soft.

Step 5

Make the optional Avocado Sauce ( see notes)
