For bivvy sessions, after allot of contemplation and trials & taking all things into account such as preparation, taste, health aspect (-yes-) and how much to carry and wash up after ... I have concluded that its pasta with pesto and salad in the evening and Porridge with honey in the morning.
Pasta should be those stuffed fresh Tortellini ones in that come in the transparent plastic trays with the peel off top in the supermarket Refrigerated section and a jar of Pesto sauce. Salad is the prepacked pre-washed ones. Porridge is simply dry porridge oats, a small sqeezy bottle of Honey and some milk. You will also need 1 pot, 1 fork and of course a stove and some water.
Now heat your water till it boils then tip the Pasta into it and cook for 5mins. Stir with your eating fork. The now empty plastic pasta tray can house the fork to keep it clean when your not stirring. After 5 mins drain the pasta. Use the fork held against the pot to drain , dont use a separate draining utensil (less washing up after).
Now open your pesto sauce jar and pour some pesto over the cooked pasta in the cooking pot. Stir it with your fork till its all nicely covered. Open your packet of ready washed Salad and sprinkle a good handful over your pasta. You could add some ready grated Parmesan at this point if you wish.
Eat direct from the cooking pot placed onto the transparent pasta tray on your knees. The tray stops your legs getting scalded. by the pots still hot underside.
Following eating you now have just 1 pot and 1 fork to wash. Keep the plastic tray.
The following morning pour some porridge oats into the same (washed) pot. Add some milk. Heat for 3 or 4 mins and stir with the same fork as the night before. When the Porridge is cooked to a fairly stiff consistency, add a glug of Honey and stir round. Eat from the cooking pot placed once again on the plastic pasta tray from the night before. Eat with the fork (this is the reason why you made the Porridge fairly stiff...) Once again following eating you have just 1pot and 1 fork to wash.
For longer sessions the fresh pasta can be substituted for dry stuffed pasta and the salad can be substituted for small Cherry tomatoes. Reason why its got to be small Cherry tomatoes is because then you can eat them individually without having to slice them thus saving on the washing up of 1 knife after.
Pasta and Porridge - Hot, tasty, healthy, minimum preparation and little to wash up after....you know it makes sense ;-)
