Thoroughly rinse your spinach and dry completely in a salad spinner.
Heat your oil in a large heavy-bottomed skillet.
Add in garlic and cook until fragrant, for about 1 minute.
Add in half of your spinach and stir to wilt. Stir in the remaining half of the fresh spinach.
Drizzle in the fresh lemon juice and stir constantly until all spinach is just wilted.
Remove from the heat and season with lemon zest, sea salt and pepper to taste.
Serve and enjoy!
