Making grilled seafood skewers is simple when you follow these easy steps:

1. Soak Skewers: If using wooden skewers, soak them in water for at least 30 minutes to prevent burning on the grill.
2. Prepare Marinade: In a bowl, whisk together olive oil, lemon juice, garlic, paprika, oregano, salt, and pepper.
3. Marinate Seafood: Place the shrimp and scallops in a resealable plastic bag or bowl. Pour the marinade over the seafood, ensuring it’s well-coated. Let it marinate for 30 minutes in the refrigerator.
4. Prepare Vegetables: While the seafood marinates, cut the bell pepper, zucchini, and onion into bite-sized pieces.
5. Assemble Skewers: Thread the marinated seafood and vegetables onto the skewers, alternating between the two. Leave a little space between each piece to ensure even cooking.
6. Preheat Grill: Preheat your grill to medium-high heat.
7. Grill Skewers: Place skewers on the grill, cooking for 2-3 minutes on each side, or until the seafood is opaque and cooked through.
8. Serve Hot: Once cooked, remove the skewers from the grill and let them rest for a couple of minutes before serving.
