I lived in Paris for 10 years and have been back in the States for 4 months now. Frozen food exists in France but it is different in it’s acceptance by the public. For example, you can buy frozen food (usually vegetables and potato products) in supermarkets. Even sometimes pizza and frozen quiches and of course, fish (like breaded filets and shrimp) and chicken nuggets. And ice cream.
But that’s it. No preprepared frozen food like Hungry Man or Marie Callendar or whatever. Forget it. It doesn’t exist in a supermarket. I can’t believe all the stuff you can get here - individually wrapped burrito’s? Breakfast burritos? 80 different kinds of pizza? Frozen juice! Wow!
They do have a chain of frozen food stores called Picard Surgeles where you can get more things (hor d’oerves, some meals, more vegetables, and escargots). In one, I even found that they were selling bags of ice! That was the ONLY time I have ever seen a store in France sell a bag of ice. It’s a fun game, throw a party in France and invite someone you really don’t like and make them responsible for the ice. Very subtle, very wicked, very funny.
So there you have it - frozen food as you know it is just not available in France.
