Creating Texas Roadhouse Grilled Shrimp can be a straightforward process. Just follow these steps:

1. Prepare the Shrimp: In a bowl, combine the shrimp with olive oil, lemon juice, garlic powder, smoked paprika, onion powder, cayenne pepper, salt, and pepper. Mix thoroughly to ensure each shrimp is coated well.
2. Marinate: Cover the bowl with plastic wrap and let the shrimp marinate in the refrigerator for about 30 minutes to enhance the flavor.
3. Preheat the Grill: Heat your grill to medium-high heat. If using wooden skewers, soak them in water for about 15 minutes to prevent burning.
4. Skewer the Shrimp: Thread the marinated shrimp onto the skewers, ensuring they are placed close together but not overcrowded.
5. Grill: Place the skewers on the grill. Cook for about 2-3 minutes on each side, or until the shrimp turn pink and opaque.
6. Garnish: Remove from the grill and let cool slightly. Garnish with fresh parsley and serve with lemon wedges.

By following these steps, you will have scrumptious Texas Roadhouse Grilled Shrimp ready to enjoy!
