Toss the shrimp in a bowl with Cajun seasoning until evenly coated

Heat olive oil in a large skillet over medium-high heat until shimmering

Add shrimp in a single layer and cook until pink, opaque, and slightly curled

Remove shrimp from the pan and set aside to prevent overcooking

In the same skillet, melt butter and add sliced scallions

Sauté until fragrant and slightly softened, releasing a mild onion aroma

Stir in cauliflower rice and spread evenly across the pan

Cook while stirring occasionally until tender and lightly golden

Sprinkle in salt and remaining Cajun seasoning for extra flavor

Return shrimp to the pan and gently toss everything together

Cook briefly until heated through and coated in buttery spices
