"Sourdough" oatmeal

I let some of the oats from yesterday soak for a full 24 hours in the warm water/ yogurt mix. Today I cooked them up and to my delight the oatmeal tasted exactly like sourdough bread. I didn't want to over power the natural sour flavor so I just served this morning's oatmeal plain with milk. I'm now trying to wrap my palate around these lacto-fermented oats and what other flavors would go with them.
