1. 1. Start by flaking the cooked salmon filet into small, bite-sized pieces. Be sure to remove any skin or bones before gently breaking up the fish with a fork.

2. 2. In a medium bowl, combine the cooked sushi rice, mayonnaise, rice vinegar, and sesame oil. Mix everything together until the rice is evenly coated with the flavorful seasonings.

3. 3. Gently fold the flaked salmon and chopped green onion into the seasoned rice mixture, being careful not to overmix.

4. 4. Using clean hands or a small scoop, carefully shape the salmon and rice mixture into bite-sized balls, about 1-inch in diameter. The mixture should hold together easily without being too sticky or firm.

5. 5. Serve the Baby Friendly Salmon and Rice Sushi Balls as is, or add any desired toppings like avocado or cucumber. Keep the sushi balls refrigerated until ready to serve for the best texture and flavor.
