Heat 3 tablespoons of olive oil in a large skillet over medium heat. Add sliced sausage, sliced chicken and cook for about 5 minutes, covered.
Add chopped red bell pepper and green bell pepper, stir in with sausage and chicken, cover, and continue cooking for about 5 more minutes, on medium heat.
Add shrimp and cook until shrimp just turns red. Add chopped green onions.
Add spices (sweet smoked paprika and red chili powder), add just a touch of turmeric for color. Season with salt and pepper. Remove from heat and keep the skillet covered. The shrimp and green onions will continue cooking slightly when covered and off heat – without overcooking.
Cook 2 cups of rice in a sauce pan according to package instructions.
Add cooked rice into the skillet with shrimp, chicken and sausage. Mix everything well, so that olive oil, juices from spicy sausages, and other cooking juices and spices coat orzo or rice.
Add some chicken stock or water to make paella more juicy vs. dry. Keep adding more chicken stock or water to achieve the desired consistency of your paella – I think the juicier it is, the better. Add more salt and pepper if needed.
