1. Break up the cauliflower into large florets, then use your hands to break into very small florets.
2. Heat a large, heavy skillet over medium-high to high heat. Add the oil, then the cauliflower and garlic. Stir the cauliflower around in the pan, allowing it to get very brown in some areas. Cook for 3 minutes, then turn the heat to low.
3. Add the soy sauce, lime juice and most of the sliced green onions, reserving the rest for serving. Stir and allow to cook for 1 minute, then add the hot sauce and stir until incorporated. Add a little more hot sauce if you want a deeper color and flavor.
4. Serve hot in a bowl. Sprinkle the remaining green onions on top and serve with lime wedges.
