Porridge - made with oats or with brown rice flakes.
Baked beans - I have a snap pot on toast.
A sandwich made with a slice of wholemeal rye bread, a slice of ham, perhaps a gherkin or cheese. Doesn't sound like much but wholemeal rye is extremely filling and those slices are big!
Bacon with wilted spinach, broccoli, mushrooms etc, with or without toast.
Continental cold meats - salami, Parma ham etc again with or without bread.
A bowl of instant miso soup with spinach thrown in plus half a baked sweet potato. Maybe throw in some tofu, too?
I really need protein in the morning so it's usually eggs for me which I know doesn't answer your question... Sometimes I have leftovers (homemade chicken nuggets, lentil soup) or tins of fish (sauteed cockles)
. I am a morning person and work a long shift so I need to have a big breakfast.
