You have to decide for yourself if those spikes fit in with your plan. Making your porridge with water instead of milk makes little or no difference to its carb count.( but I know it's the authentic method).
If you don't like most of the alternatives already considered, you could try hthe ingredients if a German or austrian breakfast, i.e.
slices of cheese and cold meat with or without low carb crackers and a bit of lower sugar fruit, such as berriesand/or a handful of nuts.
I sometimes have a bit of a soft cheese like Brie, heated in the microwave until it starts to bubble, on a pyrex plate, without bread.
