I know there are all sorts of different breakfast foods. In the US people put syrup on bacon which I find totally repulsive and lots of fast food places in Europe now sell bacon and cheese croissants - equally repulsive. Many nationalities have a savory soup and so on. But to be honest "Quorn" is one of those industrial products that I find to be beyond repulsive. Despite it being "industrial vegan", I cannot imagine it being good for you. Vegan meat substitutes are hideous oxymorons.
My suggestion would be to switch to fruit with your rice. You must be able to get pretty good fresh fruit in S.A. Vary it with the seasons. Ideally try and get local stuff. The fruit for national/international distribution is not as ripe and is treated in various ways to make it last longer and look nice. Less perfect looking local fruit is most likely riper and tastier.
After eating people get dozy due to changes in blood alkalinity. If you are having a social meal over a hour or more, you might not notice but if you eat in 10 mins by yourself you will notice that you get a warm glow and feel like a snooze maybe 15-20 mins after eating. Warm milk even if it is in the form of a large milky coffee knocks me out pretty quickly for example.
The reason why so many cultures warn about swimming is I believe because as your digestive system is working hard initially after eating, you are in danger of getting stomach cramps which are clearly not a great idea in the water especially in colder countries or places where there are currents. It maybe an urban legend but there maybe some truth in it. Swimming in a cold sea or lake would not be a good place to test whether it is true or. A foot stool is certainly going to cause you to squeeze your tummy which surely won't be beneficial after a meal.
I know a number of people who just have watered down fresh lemon juice in the morning (room temperature water) or even just luke warm water first thing in the morning and don't eat for anything from an hour to four hours afterwards. Not sure of the logic but maybe you could do something similar and have "breakfast/brunch" after your guitar practice.
