Add cauliflower rice to the casserole dish and broil for 10 minutes to soften.
Once the cauliflower rice is done, set aside and preheat oven to 400.
If using pork rinds, use a food processor to crush the pork rinds. If using pork panko breadcrumbs, skip this step.
Combine all the ingredients (except for the red sauce, 2 cups cheese, and fresh basil that is set aside for the casserole) for the meatballs. I use my hands to mix all these ingredients.
Use a small cookie scoop and make small meatballs (all the same size).
Place the meatballs on a cookie sheet and bake them for 15 to 20 minutes or until the meatballs are fully cooked.
Remove them from the oven and place them on the cauliflower rice in the casserole dish.
Top with the low carb red sauce and cheese and put them back in the oven.
Bake for an additional 5 to 10 minutes until the cheese has fully melted.
