Cut your chicken breast in bite sized pieces, then saute the chicken with a tablespoon of Olive Oil in a large skillet or pot. Once chicken is cooked through, remove it from the skillet and set aside.
Saute onion in another tbsp of olive oil for 1-2 minutes or until it starts to look transparent.
Add Garlic and cook for another 30 seconds.
Add your cauliflower rice to the pot with the onion and garlic. Season with Salt and Pepper and saute for 5 minutes.
Add Chicken Broth and cook an additional 3-5 minutes.
Add Asparagus to the pot and cook for 5 minutes.
Stir in Spinach or Greens, cook for one minute or until the spinach is wilted. At this point most of the excess liquid should be gone, if not cook for an additional minute or two.
Stir everything together - Add the cooked chicken back to the pan with the lemon juice, lemon zest and Parmesan cheese.
Dish up and top with additional Parmesan cheese (optional) - Enjoy!
