Pizza dough, mashed potatoes, onions, garlic and colorful bright slices of garden tomatoes This is a wonderful hospitality pizza, perfect for summertime entertaining or winter holidays. This is great hot, cold, room temperature and I prefer it in small bites. You can also omit the potato component and shred up some raclette or camembert to top it with before it is completed baked. Pissaladiere is French pizza – where pizza really came from.
