Preheat the flat top griddle on medium-high heat (400ºF to 425ºF). Use an infrared temperature gun to check the temperature.
Prepare the vegetables while the grill is preheating. Slice the vegetables into bite-sized pieces. Add to a bowl and toss veggies with butter and season with all-purpose seasoning.
Season the grill with olive oil. Add the vegetables. To get that smoky flavor, do not move the vegetables for 2-3 minutes before flipping.
Flip the vegetables with a long metal spatula. Cook on the other side for an additional 2-3 minutes.
Taste to check for seasoning, and add more if needed before serving.
