Directions: Keto Mexican Cauliflower Rice

Step 1: Prepare the Cauliflower
Start by washing the cauliflower and cutting it into florets. This will make it easier to process into rice-sized pieces.
Step 2: Rice the Cauliflower
In your food processor, pulse the cauliflower florets until they resemble rice grains. Be careful not to over-process; you want a nice texture, not a mushy mixture.
Step 3: Heat the Skillet
In a large skillet, heat the olive oil over medium heat. Make sure it’s hot but not smoking.
Step 4: Sauté the Cauliflower Rice
Add the riced cauliflower to the skillet. Stir it around for about 5-7 minutes until it starts to soften and turn golden.
Step 5: Season It Up
Sprinkle the fajita seasoning and salt over the cauliflower rice. Mix well to ensure even distribution of the spices.
Step 6: Add Salsa and Cilantro
Pour in the salsa and chopped cilantro, stirring to combine. Allow it to cook for another 2-3 minutes until everything is heated through.
Step 7: Finish with Lime Juice
Remove the skillet from heat. Squeeze fresh lime juice over the top, giving it a final stir before serving.
