Preheat your grill to medium-high heat, around 400°F (200°C). Allow at least 10-15 minutes for the grill to heat up.

Wash and chop your vegetables into uniform pieces, about 1-inch thick.

Toss the chopped vegetables with olive oil, salt, and pepper in a large mixing bowl.

Place the seasoned vegetables directly onto the grill grates or into a grill pan. Grill undisturbed for about 5 minutes.

Flip the vegetables using tongs and continue grilling for another 5 minutes.

Remove the vegetables from the grill and transfer to a serving platter.
