Heat ½ tablespoon olive oil in a large skillet over medium heat for 1-2 minutes, until shimmering.
Add the minced garlic and saute briefly, then stir in the entire bag of spinach by the handful.
Season your spinach with ¼ teaspoon crushed red pepper, sea salt, and black pepper to taste. Once it starts wilting down, stir in a splash of lemon juice.
Saute over medium heat for 4-5 minutes, stirring often, until spinach is wilted and dark green (being careful not to overcook). Serve hot.
Notes
You can also throw in a few bacon bits for some extra smoky saltiness, if you like -- although I didn't in mine today.
