This Artichoke Rosemary Tart with Polenta Crust is a great alternative to Quiche Lorraine. Although it looks like quiche, and contains ingredients typically found in quiche, like eggs and cheese, it differs in almost every other way. The vegetarian filling is made of Greek yogurt, infused with fresh herbs, and surrounded by a delicious, gluten-free, cornmeal crust. Artichoke hearts and rosemary are the base flavors in this elegant tart but you can easily swap them out for other vegetable and herb combinations. Asparagus with dill, mushrooms with thyme, and tomatoes (technically a fruit) and basil, would all taste delicious and work well with the other ingredients in this recipe.
