Croque Monsieur: French Grilled Cheese by Mom De Cuisine

Every new place we go, we have preconceived notions of what it will be like. Some of it based on research, some based on hearsay from others, some based off of what you see on tv or movies. Our time in Paris was no exception. We thought/were told the French are curt (or rude by American cultural standards). We thought Paris would be somewhat one note:old French buildings and museums. It wasn’t. It was a melting pot of people, cultures, food, and architecture. The food-from the formal and classic to the modern and chic, somewhat was unexpected. When one thinks of dining in Paris, one may think of fancy restaurants with stuffy waiters. And yes, I’m sure those do exist.  However, we were surprised by the casualness of dining. From long lunches at simple street cafes to the myriad of food stands dotting the city and their friendly purveyors. With kids in tow snacking on street food while navigating busy streets wasn’t really feasible, but it didn’t stop us from looking. Time after time, the tastiest culinary street food always seem to be Croque Monsieurs, or the French version of a grilled ham and cheese. And after many of our misconceptions about the France and her most popular city were put to bed, one thing is still true in my mind: her food and people are effortlessly chic while remaining approachably delicious!
