Perfect the Gnocchi Base: Bring salted water to a boil, cook gnocchi until they float (2–3 minutes), then drain and pat dry on a towel.
Achieve Golden Perfection: Heat olive oil in a large frying pan over medium-high heat. Add gnocchi in a single layer and cook undisturbed for 2–3 minutes until golden brown.
Create Even Crispiness: Stir and cook another 2–3 minutes until evenly crisped on all sides.
Build Aromatic Foundation: Lower heat to medium and sauté garlic for 1 minute, just until fragrant.
Incorporate Fresh Greens: Add spinach and cook 2–3 minutes until wilted.
Season and Finish: Add salt, pepper, and red pepper flakes. Remove from heat, stir in feta, and serve immediately.
