Packing eggs can be tricky. One solution is substituting some crumbled tofu with turmeric and then go next-level with chili power or sauce.
Typically, I eat oatmeal most winter days and muesli most summer days. At home I’ll eat rolled oats and when backpacking I’ll switch to quick oats or instant oats. My own preference is plain oats with raisins as a sweetener.
