Sweet onions are essential for their mild, slightly sugary profile. Olive oil helps soften and caramelize them gently. Vegan mayonnaise and sour cream provide richness and moisture, replacing traditional dairy-based binders. Bread crumbs add structure, while vegan Parmesan contributes umami and a savory depth. Garlic powder and dried thyme enhance the overall aroma, and fresh chives offer a bright, fresh finish.
