Cook the rice according to the package. Heat the butter, oil and garlic in a large skillet over medium-high heat until fragrant, about 1 minute. Add the Cajun seasoning and shrimp and cook, stirring until the shrimp begin to curl, about 1 minute. Season with S&P.

Add the tomatoes, scallions, shallot and asparagus and cook, stirring for 4 minutes so shrimp are opaque. Stir in the parsley and serve over rice. Serve lemon wedges on the side.
