Gather all your tools and ingredients: a large wok or skillet, spatula, small bowl, knife, and chopping board.
Heat 2 tablespoons of neutral oil over medium-high heat until it shimmers and just begins to ripple, about 2 minutes.
Add the minced garlic to the hot oil and sizzle for about 30 seconds until fragrant and golden around the edges, filling your kitchen with warm, nutty aroma. Keep a close eye to avoid burning.
Quickly add the washed and dried spinach to the pan, pressing it down into the hot oil and garlic. Toss or stir vigorously to coat the leaves evenly. Watch as the greens wilt rapidly, turning a bright, glossy green within 1-2 minutes.
Season the greens with a pinch of sea salt or a splash of soy sauce, stirring well to distribute the seasoning evenly. Continue tossing until the greens are tender and fragrant.
Remove the pan from heat and squeeze a little fresh lemon juice or splash rice vinegar over the greens for a bright, zesty contrast. Give everything a final stir.
Transfer the vibrant greens to a serving dish, and if desired, sprinkle with chili flakes for a touch of heat. Serve immediately while warm and fragrant.
