Begin by bringing a large pot of salted water to a rolling boil over high heat. Add the gnocchi and cook for about 2-3 minutes, or until they rise to the surface. Drain and set aside.

In a large frying pan, heat enough olive oil to coat the bottom until shimmering, about 2 minutes.

Gently add the cooked gnocchi in a single layer to the pan and let them cook undisturbed for about 2-3 minutes until golden brown and crispy. Stir and cook the other sides for another 2-3 minutes.

Reduce the heat to medium and add the minced garlic. Sauté for about 1 minute until fragrant.

Add the fresh spinach to the skillet and stir. Cook until wilted, about 2-3 minutes.

Season the mixture with salt, black pepper, and red pepper flakes, stirring to distribute evenly.

Remove from heat and gently mix in the crumbled feta cheese. Serve immediately.
