after Vegies are cut use a couple 1 gallon freezer bags to apply powderd seasoning (think shake and bake but more gentle as not too mush Vegies)

before arranging Vegies in pan lightly coat pan bottom with olive oil using a papertowel. Then lay in dense Vegies first and mushrooms and broccoli towards top. add more powdered seasonings if desired

Butter should be cut in pats and each pat quartered. Generously place it throughout dish on top middle and sides of contents. If grilling is going to be immediate or with in a couple hours of prep add wine after butter. If peeping night before wait to add wine til closer to cook time. pour wine across top of Vegies in middle of pan slowly so not to rinse off powders. cover with heavy duty aluminium foil crimping around lip of pan to make a good seal. If using a outdoor propane grill turn heat on med and set on one side takes about 10-15 min to steam Vegies and melt butter unless wine was cold then depending on grill more time is needed.

Whilst grilling avoid opening foil for at least 10 min so steam can build and butter can melt. if unsure of grill lower heat or move pan up on wire rack if it will support it. if you prefer softer mushy servings leave over heat longer. after removing keep covered for a couple min so as not to get burned from steam before serving.
