place the first 7 ingredients on the above list in a large glass mixing bowl.
wearing food-safe disposable gloves, mix and squeeze through your fingers until you have a meat 'dough'.
take a small quantity of meat 'dough', press it and roll it between your palms to make small balls (about 4cm diameter - you should end up with 24, give or take a couple).
incorporate the meat balls, put the lid on and turn heat down to medium-low.
should the tomato sauce start becoming too dense, add a little water (20-30 ml at a time) - but don't overdo it as you don't want to end up with a watery sauce.
cook for 30 minutes, turning the meatballs over half way through cooking.
minutes before the end of cooking time, taste test and adjust seasoning as required.
to cook the cauliflower rice, simply place it in a microwave-safe bowl, and blast it on high for 2 minutes, then stir and repeat.
Notes
You can make the meatballs as spicy as you like, by adding some chopped chillis and cayenne pepper to the meat mix. Leftovers can be stored refrigerated for up to 3 days, or you can freeze individual portions.
