Rice the cauliflower: If using a whole head, cut into florets and pulse in a food processor until rice-sized. Don’t overprocess, or it can turn mushy.
Make the lime crema: In a small bowl, stir together sour cream, lime juice, and a pinch of salt.
Thin with water to a drizzly consistency. Set aside.
Sauté the onions and garlic: Heat 2 tablespoons oil in a large skillet over medium heat. Add onion and cook 3 to 4 minutes until soft.
Stir in garlic and cook 30 seconds until fragrant.
Brown the turkey: Add ground turkey. Cook, breaking it up with a spatula, for 5 to 7 minutes until no longer pink.
Season the meat: Sprinkle in chili powder, cumin, smoked paprika, oregano, chipotle or cayenne (if using), salt, and pepper. Stir well to coat.
Add moisture and simmer: Pour in the chicken broth.
Simmer 2 to 3 minutes to let the flavors meld and keep the turkey juicy. Finish with lime juice. Taste and adjust seasoning.
Cook the cauliflower rice: In a separate skillet, warm 1 tablespoon oil over medium-high heat.
Add cauliflower rice, garlic powder, and salt. Sauté 4 to 6 minutes until tender but not soggy. Turn off heat, then stir in lime juice and cilantro.
Prep the toppings: Dice avocado, halve tomatoes, slice jalapeños, and chop cilantro.
Shred cheese if not pre-shredded.
Assemble the bowls: Add a bed of cilantro-lime cauliflower rice. Top with seasoned turkey, tomatoes, avocado, cheese, red onion, jalapeños, and a drizzle of lime crema. Finish with extra cilantro and lime wedges.
Serve: Enjoy warm.
If meal prepping, keep the cold toppings and crema separate until serving.
