Greek veggie lasagna is a delicious and unique twist on the classic recipe. Layers of lasagna noodles, roasted vegetables like eggplant, zucchini, and red onions, and a tangy tomato sauce are topped with crumbled feta cheese and Kalamata olives. The combination of flavors creates a lasagna that is both hearty and refreshing, with the salty feta cheese and olives adding a burst of Mediterranean flavor.
