Portobello Stacks

Portobello Stacks layer balsamic-kissed mushrooms and sweet onions with hearty eggplant, juicy tomato, and melted provolone for a savory, oven-baked bite. The tang of vinegar balances the earthiness of the vegetables, while the cheese bubbles to a golden finish. Serve as a satisfying vegetarian dinner or an elegant side for a relaxed weeknight or casual gathering.
