I think I'm going to have to try that black pudding bannock it looks incredible... and you can get some surprisingly good vegge black puddings and haggises too.
Since I'm usually hiking and I like to start walking good and early I'll usually munch on a bag of dry cereal while I'm waking up/packing down. Sometimes if I've made it up the night before on the fire I'll have Knackebrot with some (vegge) pate... I rely purely on fire for cooking when I'm out so I rarely do warm breakfasts when its warmer.
In the winter on cold mornings I like to do a quick fire in my hot tent to coax me out my sleeping bag, so in those situations I'll put on a pot of porridge. When you have a hot tent you can light the fire and make breakfast without even leaving your bed, its heaven!!
Sometimes I like to eat well in the woods and I love making various unleavened breads but I usually save that for the evening when I have some free time. Breakfasts and lunches out in the wild are purely a way of fuelling my body, I have more important things to be doing then.
