- Dice fish and place in a mixing bowl. Add tomato, onion and green onions; toss gently to combine.
- Mound salmon mixture onto each avocado half. Garnish with cilantro or chives and serve immediately.
Note: If onion is not sweet, soak the diced onion in cold water for 10 minutes to remove bitterness.
Serving Suggestion: Serve with crostini.
*Large avocados are recommended for this recipe. A large avocado averages about 8 ounces. If using smaller or larger size avocados adjust the quantity accordingly.
