There's little that can top lasagna when it comes to pure unadulterated comfort food. This delicious spinach lasagna recipe is a tried-and-true classic lasagna with no meat. Instead, this one has layers of ricotta and mozzarella cheeses, your favorite purchased or homemade marinara sauce, lasagna noodles, and spinach. Serve this flavorful lasagna with crusty bread for a fabulous meal. We like it with garlic bread and a simple tossed salad. Lasagna can be a bit of a project to prepare, but the results are so worth it. And as a reward, it makes a lot, so it's great for a potluck or family meal. You can also freeze and reheat it for later, too. If you can save some room for dessert, a nice light choice for dessert after this lasagna could be fresh fruit, sorbet, or gelato.
