Firstly the healthy one. Blueberry pancakes. Made with buttermilk and served with lemon and golden syrup. And icing sugar. So not that healthy then.
And now for a daily calorific meal in one sitting. This was after a very long day. So it is a 3 egg/2 cheese omelette with 4 slices of bacon. 4 is a good number of bacon in a sandwich. 3 is the minimum, 5 is greedy but 4 is just right. I ate this as a sandwich but if you wanted to cut out the carbs I'm sure you could eat it with a knife and fork.
I'm pretty sure it has enough calories to keep you going for the day. I had it as a breakfast/lunch. Then had a nap, then went for a cross country run and it kept me going for 90 minutes. Wasn't even that hungry after the run either. You could conquer the world with cheese and bacon.
Update: This sandwich also works with sausages and sweet chilli sauce. The omelette is essential:
