Add bite-sized 1.1 pound boneless chicken, to a chopper or food processor and pulse 2-3 times until it resembles coarse mince.
Then, add 2 teaspoons garlic powder, 1 teaspoon onion powder, 1½ teaspoon dried oregano, 1 teaspoon paprika, ¼ teaspoon cayenne pepper, 1 tablespoon lemon juice, 1 teaspoon lemon zest, ¾ teaspoon salt and ½ teaspoon freshly ground pepper and process until combined. you may find a few coarse minced meat, that's fine.
Transfer the chicken mixture to a clean bowl, add 3 tablespoons melted butter and mix.
Take approximately 1 tablespoon of chicken mixture and slightly press it with your fingers to form a nugget. Do not worry about the shape.
Shape the remaining mixture into nuggets, place them on a lined sheet pan, and pop them into the freezer for 30 minutes.
Season ½ cup plain flour with ⅛ teaspoon salt and ⅛ teaspoon freshly ground black pepper and mix.
Coat each chicken nugget well with flour, then dip into the egg and finally coat with panko breadcrumbs.
Repeat the same for all the nuggets. At this stage you can fry them directly, I usually refrigerate them for 30 minutes and then deep fry them.NOTE: If you plan to freeze the nuggets for later use, spread them onto a parchment-lined sheet pan such that they do not stick to each other. Pop into the freezer and freeze for 2-3 hours. Once the nuggets are frozen, gather them all, place them in a ziplock bag, and freeze. Heat enough oil in a deep pan or a pot. Once the oil is hot, carefully slide in the nuggets. Deep fry on medium-high heat for 6-7 minutes or until golden brown and crisp.
Remove them using a slotted spoon. Fry the remaining nuggets similarly.
Serve them hot and crisp with ketchup or dip of your choice.
