Dice chicken, slice sausage, and prepare shrimp. Chop vegetables and have spices on hand.
In a large skillet or pot over medium heat, add olive oil or butter. Brown chicken and sausage pieces until slightly golden. Remove and set aside.
In the same skillet, add diced onions and bell pepper. Sauté until they begin to soften. Add garlic and cook for another 1-2 minutes, or until fragrant.
Return the chicken and sausage to the skillet. Add drained tomatoes, smoked paprika, cayenne pepper, oregano, salt, and pepper. Stir well, ensuring everything is well mixed.
Stir in the cauliflower rice, ensuring it's well mixed with the meat and vegetables. Let cook for 5-7 minutes, until the cauliflower rice is tender.
Add shrimp to the skillet and cook until they turn pink, about 3-5 minutes.
Once everything is cooked through, check seasoning and adjust if necessary. Serve hot, garnished with chopped green onions and parsley.
