Step 1

Whisk together 1/2 cup lime juice, 1/4 cup lemon juice, and 1/4 cup orange juice in a medium glass bowl. Add the diced salmon to the citrus mixture and gently toss. Make sure the fish is completely covered in the juices with some room to move. If it's not, add more of the juices.

Step 2

Place the salmon and citrus mixture in the fridge to "cook" for 30 minutes to 2 hours.

Step 3

Remove the salmon from the refrigerator and check for doneness. Drain the liquid and throw it away.

Step 4

Toss together the marinated salmon, tomato, red onion, cilantro and pepper in a fresh bowl. Add the last 1/4 cup of lime juice and 1 tablespoon of lemon and orange juice. Gently toss together.

Step 5

Carefully fold in the avocado. Add more salt, if desired.

Step 6

Serve immediately with chips, crackers or toasted baguette.
