Creating Sausage & Shrimp Kabobs is straightforward if you follow these steps:

1. Soak Skewers: If using wooden skewers, soak them in water for at least 30 minutes to prevent burning.
2. Prepare Marinade: In a bowl, whisk together the olive oil, lemon juice, garlic powder, paprika, cayenne pepper, salt, and black pepper.
3. Marinate Shrimp: Add shrimp to the marinade, tossing to coat. Let it marinate for about 15-20 minutes for the best flavor.
4. Prepare Ingredients: While the shrimp is marinating, prepare the sausage pieces and chop the vegetables as outlined in the ingredient list.
5. Skewer Ingredients: On each skewer, alternate between sausage, shrimp, bell peppers, and onion pieces. Leave a little space between each piece for even cooking.
6. Preheat Grill: Preheat your grill to medium-high heat (approximately 400-450°F or 200-230°C).
7. Grill Kabobs: Place the kabobs on the grill and cook for about 15-20 minutes, turning occasionally for even cooking and char.
8. Check Doneness: Ensure the shrimp turns pink and opaque; the sausages should have nice grill marks and be cooked through.
9. Remove & Rest: Once done, remove the kabobs from the grill and let them rest for a few minutes before serving.
10. Serve Hot: Enjoy these delicious kabobs immediately while hot.
