Preheat your oven to 350F and line a baking tray with parchment paper.
Place the ground chicken, panko crumbs, grated parmesan, egg, oregano, sundried tomatoes and garlic in a large bowl. Mix everything together until smooth. Let the mixture rest for 5 minutes.
Dip your fingers in a small bowl of water before shaping the meatballs to prevent the meat from sticking to your hands while shaping. Shape between 20-24 meatballs, around 1 inch in diameter.
Place the meatballs on the prepared baking tray and bake in the preheated 350F oven for 16-18 minutes or until they reach an internal temperature of 165F.
Prepare the sauce
While the meatballs are cooking, prepare the sauce by placing a large skillet on medium-high heat.
Drizzle the olive oil in the skillet and add the finely chopped shallot (or onion), garlic, and sundried tomatoes. Cook for 2-3 minutes or until the shallots are translucent. Add the spinach and cook, just until fully wilted.
Deglaze the skillet with the white wine and let it simmer for 2 minutes. Continue by adding the chicken broth and then the heavy cream and the salt.
Bring the sauce to a simmer and add the gnocchi to the skillet. Turn the heat down, just to keep the simmer, and cook the gnocchi for 3 minutes or as directed on the package. The gnocchi will cook and the sauce will thicken at the same time. When ready, take off the heat.
Serve the gnocchi and the sauce with the cooked meatballs and garnish with freshly grated parmesan. Enjoy!
