Add the ground chicken, egg, Italian seasoning, paprika, 2 garlic cloves, and parsley to a mixing bowl and mix with clean hands to combine. If you prefer a firmer meatball you can add 1/3 cup of ground almonds to the mix.
Rub a bit of olive oil on the palms of your hands to keep the mixture from sticking to your hands. Roll into 15 meatballs (re-oiling your hands if necessary). Place the chicken meatballs on a parchment paper lined baking sheet and refrigerate for 10 minutes.
Add 2 tbsp of olive oil to a non-stick pan and cook the meatballs for 10-12 minutes, carefully rotating until golden on all sides and cooked through. Remove the meatballs from the pan and set aside in a covered bowl to keep warm.
To the same skillet, add the remaining 1 tbsp of olive oil, butter, lemon juice, lemon slices, white wine, and capers. Using a rubber spatula, scrape any bits stuck to the bottom of the pan. Cook for 3-4 mins or until the liquid has reduced by one third. Season to taste with more salt and pepper.
Add the meatballs back to the pan and toss to cover in sauce. Cook for about 2 minutes to warm everything through. Garnish with fresh parsley and serve.
