Preheat your oven to 425°F (220°C) and prepare a baking sheet with a silicone mat or parchment paper.
In a mixing bowl, whisk together the seasoned breadcrumbs, Pecorino Romano cheese, garlic powder, dried dill, cayenne pepper, sea salt, and black pepper until well combined.
Take each salmon cube and dip it into the beaten egg, letting any excess egg drip off, then roll it in the breadcrumb mixture, pressing firmly to ensure an even coating. Arrange the coated salmon nuggets on the prepared baking sheet.
Lightly brush the tops of the nuggets with avocado oil to enhance their crispiness during baking.
Bake in the preheated oven for about 15-18 minutes, or until the salmon is fully cooked and the outside is a delightful golden brown.
For an extra touch, sprinkle with chopped chives just before serving.
