Preheat your oven to 375°F (190°C).
Flake the salmon fillets into small pieces in a large mixing bowl. Add in the breadcrumbs, egg, chopped herbs, lemon juice, garlic powder, salt, and pepper; mix until everything is well combined.
Using your hands, form small balls about 1 inch in diameter from the mixture you've prepared. Place them on a parchment-lined baking sheet to prevent sticking.
Bake the formed salmon balls in your preheated oven for 20-25 minutes or until they turn golden brown and are cooked through.
While your salmon balls are baking, prepare the creamy avocado sauce by blending together ripe avocado, Greek yogurt, lemon juice, salt, and pepper until smooth.
Once your salmon balls are done baking, serve them warm alongside the creamy avocado sauce for dipping.
