There are usually 10 aisles of meat/meat-related products, and 1/2 aisle of "not meat" products (exaggerated to make my point.) Meat and dairy lobbies are very strong in France, and it's obvious from ads/store aisles.

So I'm pleasantly surprised to see an ad from a French supermarket that is not trying to sell you more turkey, sausage, and beef for Christmas but rather focuses on vegetables.

What do you mean? The will be an aisle with ham, sausage etc, and a butchery. There will be one for canned food, which will include some tuna, cassoulet and raviolis.

In my SuperU meat is not overly present.

The supermarkets I use aren’t like yours then.

There is way more surface dedicated to meat and dairy than to their alternatives. Typically it’s rows of freezers and fridges for meat and dairy, and a third of an alley for alternatives.

Ah, I misunderstood your comment, sorry. I thought you were comparing meat & dairy to anything else (vegs, canned, ...).

Yes, there are not many alternatives, half an alley in my case.
