Warm the pan: Heat a large skillet over medium heat.
Add 1 tablespoon of olive oil and let it shimmer.
Sauté the aromatics: Add the diced onion and bell pepper. Cook for 4–5 minutes, stirring, until softened and lightly golden. Add the garlic and cook for 30 seconds, just until fragrant.
Brown the turkey: Push the veggies to the edges.
Add the ground turkey to the center with a pinch of salt and black pepper. Cook, breaking it up with a spoon, until no longer pink and lightly browned, about 6–8 minutes.
Season it up: Stir in cumin, smoked paprika, oregano, and red pepper flakes if using. Toast the spices for 30–60 seconds to wake them up.
Add depth: Mix in the tomato paste and cook for 1 minute.
Pour in the chicken broth, scraping up any browned bits from the bottom of the pan.
Stir in cauliflower rice: Add the cauliflower rice and toss to combine. If using frozen, break up any clumps. Cook uncovered for 5–7 minutes, stirring occasionally, until the cauliflower is tender and most of the liquid is absorbed.
Greens and brightness: Fold in the spinach or kale and cook until just wilted, about 1–2 minutes.
Add lemon zest and a squeeze of lemon juice. Taste and adjust salt and pepper.
Finish and serve: Turn off the heat. Stir in chopped cilantro or parsley.
Drizzle with a little more olive oil if you like. Serve hot with your favorite toppers.
