I know what you mean. Reading through these numbers makes it seem like sub 6 is common among T1s, but this thread is far from a random sample.

That much bread does sound challenging to dose for.
Greek yoghurt can be good for a low prep low carb but still calorific breakfast. Eggs are great - for speed those little pots for microwaving them can be good. Overnight oats are cheap and easy - they do give me a substantial raise in BG, but at least it's slower than bread.
