Heat the oil (1 tablespoon) over medium-high heat in a large skillet (preferably non-stick).
Add the minced clove of garlic; sauté for one minute or until fragrant.
Add the lemon juice and the spinach. Sauté for 3-4 minutes, or until greens are wilted (but not browned).
Remove from heat and season with salt and pepper to taste. Serve immediately.
