Heat the olive oil in a large skillet over medium-high heat.
Slice the chicken sausage into rounds and add to the skillet, browning for 3-4 minutes until golden.
Remove the sausage from the pan and set aside.
Add the diced onion, bell pepper, and celery to the same skillet and sauté until the vegetables are tender.
Stir in the minced garlic, smoked paprika, oregano, sea salt, black pepper, and cayenne pepper, cooking for 1 minute to release the oils.
Pour in the tomato puree and chicken broth, stirring to deglaze the bottom of the pan.
Add the browned sausage, raw shrimp, and pre-cooked brown rice to the skillet.
Simmer for 3-5 minutes until the shrimp are pink and opaque and the sauce has reached your desired consistency.
Serve immediately while hot and flavorful.
