im touring at the minute, with the same trangia burner as you i guess. Dont buy them ready in 2 minute pasta meals. You would need 6 of them and some to fill u and they taste crap.
My fav is Pasta, tomato puree, chili powder, and fried eggs if im fancy.
We also eat mashed potatoes, cut the potatoes really small and they boil quick. We had shredded bacon in mashed potatoes with curry sauce.... nice but we were hungry.
I was a bit luxurious cause i like my coffee and took our cafetera italian coffee jobby with us; the one where the water pushes up through the coffee, its ready in no time.
The frying pan on trangias are messy. So if ur short on water, dont use. U got loads, and can wash; use it.
Humm... COUS COUS.. Ang and me llove that too.. AND it uses hardly ANY water, and there is no waste!!
