First I did not say I ate Noodles or lyophilized food.

My diet was, eat pasta dressed with sauces or vegetables (pasta at the peasant), salads of various kinds, sandwiches, grilled food and more.

It may be odd, but even if I am Italian, and I have a great culinary culture, I can be a humble person who wants to confront other travelers of different cultures who can teach me something about their eating habits.
To think that being Italian no one can teach me anything about food, it is arrogant and stupid.

For example, someone might have answered that eating hazelnuts, nuts, almonds, on the road is very important because they are foods rich in vitamins and nutrients, and that coconut oil is a great nutritional supplement.

Also as told by someone, if I did my own food preparation, my budget was limited.

The fact that the diet during the trip is conditioned by what the geographic region offers is normal. But maybe you can tell me that in October in Morocco, you can prepare a certain dish. Or if you go to Greece it's easy to find feta and you can easily prepare yourself a Greek salad.

I understand it's an odd question, and for many to cook and have a varied diet during a trip it's easy. But if I did this particular question is because I want to expand my knowledge of the traveling kitchen, which is very different from what you can do at home.
