Step-by-Step Instructions:

1. Make the Chimichurri:
   • In a bowl, combine the chopped parsley, cilantro, minced garlic, red wine vinegar, olive oil, oregano, and red pepper flakes (if using).
   • Add salt and pepper to taste and stir well.
   • Let it sit for 10 minutes to allow the flavors to meld together.
2. Prepare the Steak:
   • Season the steaks generously with salt, pepper, and a drizzle of olive oil.
3. Prepare the Shrimp:
   • Toss the shrimp with olive oil, smoked paprika, minced garlic, salt, and pepper, ensuring they are evenly coated.
4. Grill the Steak and Shrimp:
   • Heat a grill pan or skillet over medium-high heat.
   • Grill the steaks for about 4-5 minutes per side for medium-rare, adjusting the time for your preferred doneness.
   • Grill the shrimp for 2-3 minutes per side until they turn pink and opaque.
5. Serve:
   • Plate your sizzling steak and shrimp. Drizzle the chimichurri sauce over the steak and serve the extra sauce on the side for dipping.
   • Garnish with additional herbs for a fresh, vibrant finish.
