Here's my typical breakfast routine:
I put my kettle on.
While kettle is boiling, I use a 225 mL scoop to add 1 scoop of oats and 1 scoop of soya milk to a pyrex bowl.
Kettle boils.
Fill thermos mug with boiling water to pre-heat it. Put lid on mug to keep the heat in.
Add dried fruit to bowl (raisins, sultanas, pieces of dried apple, apricot etc.).
Add a teaspoon of Orange Blossom honey to bowl, and a tiny pinch of salt (the smallest amount that I can still taste).
Reboil kettle. Pour off-boil water from mug into scoop to wash out dregs of soya milk and tip that over the spoon to wash the honey into the bowl.
Discard rest of water from mug, put teabag in and fill with boiling water from kettle. Put lid on mug.
While tea is brewing, stir contents of porridge bowl and cover with a pyrex lid (to contain any minor porridge eruptions that may occur in the microwave).
Microwave on full power (1 kW) for 2 minutes and 10 seconds. Stir contents of bowl. Microwave for another 1 minute and 10 seconds. These timings were arrived at by experimentation and suit my microwave, and the quantities and method that I employ. You will have to work out your own timings. If you overheat the porridge in a microwave, you'll end up with a gloopy mess to clean up!
During the finally cooking phase, I take the teabag out of the mug and add milk. Replace lid on mug. That's one perfectly brewed mug of tea, and it will stay hot long enough for me to eat my porridge.
When the porridge is done, I chop a ripe banana into it.
I can happily last 8 hours and a 40 mile bike ride on that breakfast.
PS My porridge consistency is such that a tablespoon inserted vertically into it takes about 5 or 6 seconds to fall over i.e. thick, but not solid.
