Sauté the garlic. Heat olive oil in a medium sauté pan over medium heat. Add sliced garlic and cook for 1–2 minutes, stirring often, until lightly golden and fragrant.
Wilt the spinach. Add spinach to the pan and toss continuously with tongs until wilted, about 1–2 minutes.
Season and serve. Season with salt and pepper to taste. (I just use a generous pinch of each.) Feel free to add a squeeze of fresh lemon juice, too, if you’d like to brighten up the flavor.
