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, about 1 inch. Add to a large bowl and toss veggies with melted butter and season with all-purpose seasoning.
Season the grill with enough olive oil to prevent sticking. Add the vegetables to the griddle. To get that smoky flavor, do not move the vegetables for 2-3 minutes before flipping. This will allow a little charring to occur and provide more flavor. Flip the vegetables with a long metal spatula. Cook on the other side for an additional 2-3 minutes.
If the vegetables look nicely sauteed, then test the zucchini and asparagus by piercing them with a fork. If the fork slides in easily then the zucchini and asparagus are ready. Taste to check for seasoning, and add more if needed before serving.
