Heat oil on medium high and add garlic. Lightly roast garlic, to flavor oil. Do not brown. Cook until fragrant (30 sec – 1 min).
Add spinach. Sprinkle with salt and pepper.
Stir spinach in oil until all leaves coated in oil. Keep stirring spinach in oil until all the leaves are wilted and coated in oil. Take care to separate clumps. (About 2-3 minutes)
One bag of spinach will reduce to small portion. I recommend buying a large box and doing several rounds.
Goes well with rice.
