Old habit do indeed die hard. When my husband and I were cycling around the world, we would get through so much porridge oats, bread and pasta that we could hardly carry enough at times and always made sure we had a spare loaf of bread, a spare packet of spaghetti (took up less space than pasta and we got used to breaking it up prior to cooking up to made it easier to eat with a spork) and a packet of tortilla wraps (long life and great emergency food for when we had not been able to get bread).
I still find it hard to cut back on the amount of carbs we eat when he is around. Our homemade bread is around 250-275 calories per 100g and 100g is not very much!
I thought you were just being humorous when you said "went off to try to cycle around the world"...now I see it goes to a blog. What an adventure!
