French Onion Tart

"The onion tart is a classic dinner meal from north France. This traditional dish is vegetarian and prepared with either a shortcrust or puff pastry. I give the option to make this dish from scratch or to make it with ready-made pastry dough. The recipe is otherwise rather quickly prepared and you can serve this as a dinner meal with a green salad and tangy french dijon mustard vinaigrette dressing. The dish is vegetarian and a super budget-friendly, easy to my pocket, dinner idea. You will need eggs and of course, a whole bunch of french onions. Bring the French countryside to your home! "
