Camping pasta: Have Swiss egg helix pasta, exactly the right amount of water, some bouillon powder, triple concentrated tomato paste, pepper and a dash of cream. Cook till soaked up (takes 10 minutes). Serve with slices of gruyère.

(This is sacrilegous but done right it tastes very good and is simple to cook, you need only one pot and it is done quickly even on camping gas.)

I bought a 400g can of triple concentrate thinking it was chopped tomatoes (I'm in Greece, I do not speak Greek). It is fate. Gruyère sounds good, thanks for sharing!
