Take your food processor and attach the shredding attachment. Run florets through the shredding attachment so cauliflower is riced. You can also add the florets to the bowl of the processor and pulse, or grate florets by hand using a box grater. If you are using store bought cauliflower rice, you can skip this step.

Heat a large sauté pan over medium heat. Add olive oil. Once hot, add diced onions and sauté for 5 minutes until translucent, stirring occasionally. Add garlic and cook for another minute.

Next add the cauliflower rice. Cover and let cook for 8-10 minutes, stirring occasionally, until softened.

While the rice cooks, make the avocado mash. Add avocados to a large mixing bowl and mash with a fork. Stir in the jalapeño, lime juice, and salt and pepper.

Add avocado mixture to cauliflower rice and mix well. Stir in cilantro. Serve with more cilantro and jalapeño if desired.
