Once the heading is set, the restaurants come next, then look for the decent winding roads to join them up.
MRE just never enters the equation.
Reasonable ingredients are widely available, even outside of cities.
Stuff for picnics, bread, cheese or ham or sausage, tomatoes, cucs or cooked beetroot and fresh fruit for pud.
Stuff for cooking simple, warm a tin (ie 2 tins for two people, not a tin of each per person) of puy lentils/canneloni/flagellet/borlotti any pulses. Add 1/2 small carton creme frais + lots of soft herbs if available. Plenty of pepper. Bread for mopping up and with the cheese. Fruit for pud and to use the last of the creme frais. Beverage to personal choice.
Stuff for slightly more drawn out cooking, peel and cook spuds, drain and put aside. Roughly chop merguez/choritzo and lightly fry off, tip on top of spuds. Peel and roughly chop 1 onion, start to fry. Chop and de seed a pepper and tomato, fry off lightly. Tip everything into the pan, stir and season if necessary, esp. pepper. Add 4 lightly beaten eggs over the top and cook gently, not stirring. Its almost a fritata.
All this on a small gas Trangia. Takes a while - maybe 30-40 minutes, but that is good chilling time you would only waste whining about the taste and texture of the mre. It is much better spent drinking - beer or wine - its an equal opportunity meal.
If you don't take a salt and pepper mill with you, steal a lot of condiment sachets on the ferry/flight/supermarket caff.
