I can't face eating at the conventional breakfast time, so my "breakfast" tends to be eaten at around 11am. I therefore switch between late breakfast food or early lunch food. (As someone else said, it sits well with the 16:8 method of eating.)
Usually though, I do overnight oats (porridge oats, layered with greek natural yogurt and frozen fruits), or VERY crispy bacon in a VERY soft white roll, or, if I am feeling very indulgent and "sod the diet", I will have two very flaky croissants.
If it's early lunch food, it's usually a jacket potato (from the canteen at work - I don't go shoving jacket potatoes in at 9.30am on the offchance that I will fancy one!), or a baguette of some kind, or some home made soup from my latest "I'm in love with" gadget - my soup maker.
