Gather and prep all of your ingredients.
In a pan over medium heat, add avocado oil, garlic, and spices (cumin and chili flakes). Fry until fragrant, about 1 minute.
Add in the diced celery and continue frying for another 1-2 minutes.
Once celery is softened, add in the ground lamb and season with salt and pepper to taste. Use a spatula to break apart the lamb to mix in well with the vegetables.
Once the lamb is browning, add in the bell pepper and continue cooking until bell pepper is soft. Remove from heat and set aside.
In a separate pan, add avocado oil over medium-high heat. Once hot, add in the cauliflower, basil, oregano, lemon zest, and salt and pepper to taste. Cook moisture out of the cauliflower, stirring frequently.
Once cauliflower rice is done, plate in a bowl with the lamb and other vegetables, then squeeze lemon juice over the top. Garnish with lemon slices if desired. Enjoy!
