Your very obviously not a fussy eater lol I am though as are camp buddies. These little pots are just water boilers really. You'd be better off just taking a can of 'All Day Breakfast' and heating the can in your pot and you have water for a brew.
There is a sliding scale of how good food tastes against how knackered you are.
Last week i ate a stone cold, dried lamb souvlaki that would have ended up in the bin 99% of the time.
We we'd just knocked out a noggin under 2000m of ascent and were about half way through a 24km hike.
Ended up being one of the tastiest meals i've ever eaten, and i don't like lamb at all
The pots are fine, it's rare i use anything bigger than 900ml even at home.
Biggest problem cooking outdoors is controlling the heat and having enough of it over a long enough time.
The rare time i've had a fire going we've done some pretty fantastic stews, i'm not a fan of everyone having fires every time we all go out though, plus i'm often above the tree line so burning trees is not an option.
It's also rare i can be bothered to spend 30mins faffing about cooking anything after a days hiking, you then have to faff about cleaning all the pots and pans, where do you get the water from when up a mountain, what do you do with the dirty run off?
So cooking on a camp site or when car camping and cooking when you're carrying all your food and cooking kit are 2 completely separate things.
As i don't car camp my advice is aimed at those that carry their food and kit.
So for me 99 times out of 100 it's either something cold (better option in Greece during the summer months) or it's something that takes less than 10 mins to make.
Have never eaten a tinned breakfast, but i'd have to be pretty desperate to try that

Tried a Wayfayrer breakfast and it was not pleasant at all
