01 - Bring a large pot of salted water to a boil. Add the gnocchi and cook according to package instructions until they float to the surface, approximately 2–3 minutes. Drain thoroughly and set aside.
02 - Heat olive oil in a large nonstick skillet over medium heat. Add minced garlic and chopped shallot, sautéing for 1–2 minutes until fragrant and translucent.
03 - Add chopped spinach to the skillet and cook, stirring constantly, until just wilted, about 1 minute.
04 - Reduce heat to low. Stir in crème fraîche or Greek yogurt, lemon zest, and lemon juice. Season with salt, pepper, and half the chopped dill.
05 - Add cooked gnocchi to the skillet, tossing gently to coat evenly in the sauce. Warm through for 1–2 minutes, ensuring everything is heated through.
06 - Remove the skillet from heat. Gently fold in smoked salmon strips, allowing residual heat to warm the salmon without overcooking it.
07 - Divide the dish among plates. Sprinkle with remaining dill and chopped chives. Serve immediately with lemon wedges on the side.
