Rice the Cauliflower: Wash and thoroughly dry the cauliflower. Cut into florets and pulse in a food processor 8 to 12 times until rice-sized pieces form. Avoid overprocessing.
Dry the Cauliflower: Spread the cauliflower rice onto paper towels or a clean kitchen towel and allow excess moisture to absorb for several minutes.
Dry Toast for Better Texture: Heat a large skillet over medium-high heat without oil. Add the cauliflower rice and cook for 5 to 7 minutes, stirring occasionally, until steam escapes and excess moisture evaporates. Remove and set aside.
Season the Turkey: Combine the ground turkey with half of the Cajun seasoning mixture and gently mix.
Brown the Turkey: Heat olive oil in a large skillet or Dutch oven over medium-high heat. Add the turkey and allow it to cook undisturbed for a few minutes before stirring. Continue cooking until mostly browned.
Cook the Vegetables: Add the onion and bell peppers. Cook for 3 to 4 minutes until slightly tender but still vibrant. Add the garlic during the final minute and stir in the remaining Cajun seasoning.
Build the Flavor Base: Add tomato paste, minced chipotle pepper, adobo sauce, Worcestershire sauce, chicken broth, Better Than Bouillon, hot sauce, and butter. Stir well and simmer for 2 to 3 minutes until glossy and flavorful.
Add the Cauliflower Rice: Return the cauliflower rice to the skillet. Let it sit undisturbed for 2 minutes to develop light color and flavor.
Finish the Bowl: Stir and continue cooking for 2 to 3 more minutes until everything is heated through and well combined.
Garnish and Serve: Top with sliced green onions, fresh parsley, and a squeeze of fresh lemon juice before serving.
