Preheat your grill to medium-high heat.
Wash and prepare all vegetables by cutting them into uniform sizes.
In a large bowl, combine the vegetables with olive oil, garlic powder, salt, and pepper.
Toss the vegetables until they are evenly coated with the oil and seasoning.
Place the vegetables on a grill basket or skewers for easier handling.
Grill the vegetables for 5-7 minutes, turning occasionally for even cooking.
Check for doneness; vegetables should be tender and slightly charred.
Remove from the grill and let them rest for a few minutes.
Garnish with fresh herbs if desired.
Serve warm and enjoy your delicious grilled vegetables!
