Clean & remove cauliflower florets from the head of cauliflower. Use grater attachment of food processor to "rice" the cauliflower. Set aside.
Heat olive oil, and saute the chopped onion & jalapeno until nearly cooked. Then add the garlic and cook until fragrant.
Once the garlic is fragrant, add the tomato paste. **Note, depending on how much riced cauliflower you have, you may need to adjust this amount. Just know your finished product will be more "tomato-y" if you use the entire 4 oz container, like I did
Add your spices to tomato & veggie mixture, and cook 1-2 minutes to blend flavors.
Once blended, add riced cauliflower, and stir well.
After cauliflower and tomato mixture are well blended, add the entire can of Rotel, and continue to stir & cook over medium heat until the moisture from the Rotel has evaporated & the cauliflower is cooked through, about 7-8 minutes.
