Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
Add the sliced smoked sausage to the skillet and cook for 5 minutes, stirring occasionally, until browned. Remove the sausage from the skillet and set aside.
In the same skillet, add the remaining 1 tablespoon of olive oil.
Add the sliced red bell pepper, green bell pepper, and yellow onion to the skillet. Cook for 4-5 minutes until the vegetables are tender-crisp.
Add the minced garlic, smoked paprika, dried oregano, and crushed red pepper flakes to the vegetables. Stir and cook for 1 minute until fragrant.
Return the cooked sausage to the skillet and stir to combine.
Add the raw shrimp to the skillet, season with salt and black pepper, and cook for 3-4 minutes, stirring occasionally, until the shrimp turn pink and are cooked through.
Remove the skillet from heat and sprinkle the chopped fresh parsley over the top.
Serve immediately.
