Finely dice the onion, thinly slice the garlic and bell pepper. Trim the tops and tips from the radishes. Quarter the radishes. Heat the olive oil in a skillet over a low/medium heat. Add the radishes, onion, garlic, and bell pepper. Sweat gently for 5 minutes until tender and fragrant.
Finely chop the rosemary. Add the rosemary, ground turkey, tomato paste, salt and pepper to the skillet. Stir well to combine. Cook over a medium/high heat until the turkey is browned all over.
Add the chopped tomatoes and chicken stock to the skillet. Bring to a boil. Reduce to a simmer and cook for 10 minutes to reduce the sauce down.
While the sauce is cooking, add the cauliflower rice to a large saucepan with 2 tablespoons of water and a pinch of salt and pepper. Set over a medium heat and cook through for 3-4 minutes or until piping hot and tender. Drain away any excess liquid.
Divide the cauliflower rice between four individual serving bowls. Top the rice with the turkey mixture. Serve hot.
