These Vegetable Flatbread Roll-Ups are a delicious, vegetarian-friendly appetizer or snack. Made with a simple base of grated potatoes and zucchini, the flatbread is baked until golden and crisp, then topped with cream cheese, caramelized onions, sun-dried tomatoes, and fresh arugula. A drizzle of balsamic glaze adds a sweet tang that brings everything together. Rolled and sliced into pinwheels, they’re perfect for parties, lunchboxes, or elegant entertaining.
