Yes! Prepare the mushrooms as outlined then spread them evenly on a parchment paper-lined baking sheet and roast in an oven heated to 350°F for 20 minutes, stirring halfway through, or until golden brown and tender. Remove the mushrooms from the oven, toss with 1 cup of BBQ sauce, then return to the oven to roast for 10 more minutes. Assemble the sandwiches as directed.
