Microwave the bag of cauliflower rice according to package directions.
Melt the butter in a large, non-stick frying pan.
Add all the seasonings, chili powder through black pepper, and cook until fragrant, for about one minute.
Add the cauliflower rice and stir to combine. Set off heat while the orzo is cooking.
In a clean sauce pan, add the chicken broth, one can full of water and half the can of crushed tomatoes. Stir to combine.
Bring the mixture to a gentle boil. Add the orzo pasta and cook for 9-10 minutes, or until tender.
Drain the orzo and add it to the seasoned cauliflower rice, along with the rest of the crushed tomatoes.
Return the pan to the heat and cook for a few minutes, stirring often.
Stir in the lime juice and serve.
