Please keep adding in salt along the way. Much of it will boil off so it's important to keep re-salting for maximum flavor.
You can use diced ginger and garlic in lieu of garlic or ginger paste.
I recommend you use fresh cauliflower and make your own "rice" - the frozen kind yields a ton of water and makes for a not so nice final dish.
Add whatever else you have in your fridge! I'll regularly add in leftover meats or will buy a whole roast chicken at Sprouts and pull apart the meat to add to my "rice."
