Food

As one might expect Israel has fabulous Middle Eastern food. However you are not going to be able to eat fresh food on the trail as much as perhaps you might like. And in Israel food is relatively expensive, although a Pita bread with Felafel and salad can make a cheap and healthy meal. These are possible infrequently in the north and barely at all in the desert.

"Falafel and salad filled Pita - so good"

Food preferences are evidently a personal choice, but they must intersect with what is both available and portable. And indeed affordable.

So for what it is worth here is my daily menu and a shopping list of the regular items that I was able to obtain. I eat a fairly simple vegetarian diet.

Treats and bonuses

From time to time I had a treat in a cafe, often at a gas station. Usually this was a coffee and a croissant or pastry of some sort.

You will feel you deserve this too.

The big bonus was that I was often given food very generously by people who saw me passing and who even called me over expressly to give me something. Nice!
