In a food processor, blend cauliflower until it reaches a rice-like consistency.
In a large skillet over medium heat, heat oil. To the oil, add the steak, onion and garlic. Cook for 5 minutes, until steak is brown. To the skillet, add the cauliflower.
In a medium bowl, whisk together the next 6 ingredients (coconut milk through lime zest) and pour over the steak mixture. Stir and cook for 5 to 10 minutes, until steak reaches desired level of doneness and vegetables are tender. To the mix, add the remaining ingredients, stir and serve warm.
