Heat pan over medium high heat, add the oil, swirling around the pan, add the onions and peppers, sauteeing until the onions are nearly translucent, about 3 minutes
Add the ground beef, browning until the meat begins to crisp, and the moisture has absorbed
Add in the taco seasoning, water and stir to combine, then add cauliflower rice, and stir again *the cauliflower rice will release additional moisture, be sure to allow it to evaporate (about 3 minutes)
Once the moisture has absorbed, and you are ready to remove from heat, squeeze the lime over top, and serve as desired
