So I've never been a fan of the sickly sweet oatmeals and other western style breakfast cereals, especially those with lots of sugar, so I've started recently getting into savory oatmeals and other porridges. My favorite so far is using a base dashi stock, miso paste and chili oil alongside some chopped light vegetables such as kimchi and scallions (water spinach is also good when finely diced).
Natto is one of my fav additions and is a great protein boost as well as giving some funky cheesy notes without using cheese
