Start with cooked, plain cauliflower rice and add this to a 9 inch pan or skillet (or closest option that you have) on the stovetop. You'll then add the diced onion, salt, garlic, and cumin. You can add a bit of avocado oil (or oil of your choice) if you want but I don't find it necessary.
Once you have all of those ingredients in the pan add the tomato sauce and bouillon. I like to dissolve the half of the bouillon cube being used in the pan with the tomato sauce or you can even do this before adding the bouillon to the pan. Then, fill the pan about a half inch from the top with water. It should take about 1 1/2 - 2 cups of water to do this. You'll simmer this on medium high or so for about 30 minutes. You're cooking the rice until almost all of the liquid is cooked out so that you have the consistency of the rice in these pictures. It won't be dry but there won't be any excess sauce.
Add any extra salt, garlic, or cumin to best suite your taste! Or even add in other flavorings to make this more of your own.
