Toss the shrimp, sausage, zucchini, yellow squash, asparagus, red bell pepper, Cajun seasoning, olive oil, salt, and pepper together in a large bowl.
Heat a skillet over medium-high heat and add the shrimp and sausage mixture. Cook for 5-7 minutes, or until the shrimp is pink and the vegetables are tender.
Serve immediately with optional parsley garnish. You can also serve it over rice or quinoa, or as a low-carb option for meal prep.
