Making Grilled Shrimp Kabobs is straightforward if you follow these steps:

1. Prepare the Marinade: In a bowl, mix together the olive oil, lemon juice, garlic powder, paprika, cumin, salt, and pepper.
2. Marinate the Shrimp: Add the shrimp to the marinade, ensuring each piece is well coated. Let it marinate for at least 15 minutes.
3. Soak Skewers: If using wooden skewers, soak them in water for about 10 minutes to prevent burning on the grill.
4. Prepare Vegetables: While the shrimp marinates, cut the bell pepper, red onion, and zucchini into pieces suitable for skewering.
5. Assemble Kabobs: Thread the marinated shrimp and pieces of vegetables onto the skewers, alternating as desired.
6. Preheat the Grill: Heat your grill to medium-high.
7. Grill Kabobs: Place the skewers on the grill and cook for about 10-12 minutes, turning occasionally, until the shrimp are opaque and cooked through.
8. Serve Immediately: Remove from the grill and let cool slightly before serving.
