I don't have a usual breakfast - it usually depends on what my current low carb dietary experiment is - at the moment I normally don't eat until lunch time.
But on Sundays I always have a BIG breakfast with my husband as his working week starts at noon on Sunday until 11pm. He needs a good breakfast before starting work as he often forgets / doesn't have time to eat while at work. Sunday breakfast is eggs, bacon, low carb sausages, mushrooms fried in butter and baked beans. Occasionally we change it up with black pudding, grilled tomatoes or Halloumi.
We eat this occasionally for lunch but couldn't face it first thing in the morning. Having said that it is 1am and I could eat it right now!
