Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
Add the sliced turkey sausage to the skillet and cook for 4-5 minutes until browned on all sides. Remove the sausage from the skillet and set aside.
In the same skillet, add the remaining 1 tablespoon of olive oil.
Add the diced red onion and minced garlic to the skillet and sauté for 2 minutes until fragrant and slightly softened.
Add the diced red bell pepper, yellow bell pepper, zucchini, and yellow squash to the skillet. Cook for 5-6 minutes, stirring occasionally, until the vegetables are tender-crisp.
Season the vegetables with smoked paprika, dried oregano, crushed red pepper flakes, salt, and black pepper. Stir well to combine.
Add the raw shrimp to the skillet. Cook for 3-4 minutes, stirring occasionally, until the shrimp turn pink and are cooked through.
Return the cooked turkey sausage to the skillet. Stir everything together and cook for an additional 1-2 minutes to heat through.
Remove the skillet from heat and sprinkle with chopped fresh parsley.
