Just checked at what a palaver and it's funny to see how the parents aren't eating vegan or even vegetarian when they're on their own:
extract from their trip from France to Spain:
" For dinner, we knocked up tinned sardines, couscous and cauliflower rice on the camping stove, which was surprisingly tasty. "
And they said they ate some cheese and baguette in a small town. Later few mentions of seafoods, roasted chicken, more oysters, anchovies, tuna, prawns, dairy products, and it's not like a one time, she mentionned that eating prawns was a habit. And they also look surprisingly normal in that blog, maybe being away from the crazy helped.
Now, I'm can't say for all villages in France but you rarely find vegetal cheese in more rural places, people aren't fond of these fake stuff. And sardines... I'm pretty sure Alan, Lola and Clara were happy to be far away from their daughters.
