If I don't have grains I pass out at lunch. It doesn't matter how many coffees I have. No grains = midday siesta. So it's pretty much flakes + muesli every morning unless I'm confident I don't need to be awake in the afternoon.
Home-made spelt sourdough toast with Vegemite/promite on one piece, and jam or honey on the other. Weekends are bacon and eggs in rolls, wraps or toasted sandwiches, or pancakes.
I only generally eat breakfast if I'm not at home. If I'm on the road I'll grab a big bbq brekkie wrap from Hungry Jacks (I LOVE breakfast wraps and I wish more places did them) and a coffee, often iced coffee, or if I'm at a cafe I'll usually get an eggs benny and a coffee.
Yogurt + stuff most days. Stuff is some combo of berries/fruit/nuts/seeds. I make my own granola because store bought is so expensive and I can't eat oats. This is my usual work breakie because I can chuck it in a jar the day before and it all mixes together.
If I need more ommph and I am at home: fry tomato/spinach/mushies and then pour two whisked eggs (plus salt and pepper) over the top and a handful of pre grated cheese. Easy omelette.
If I need a hug I make two boiled eggs with Vegemite and butter toast soldiers.
I used to eat porridge every day but now I am no oats I miss it. You can get closest with buckwheat but it's not the same.
