1 to 1-1/4cupskombuchaany flavor, homemade or store-bought (Base the amount of kombucha on whether you want a little leftover in the oats in the morning or you prefer your oats on the drier side.)
Place oats in mason jar with lid, or other preferred bowl.
Stir in optional buckwheat flour.
Add kombucha. (It may foam a bit. If you used the buckwheat flour, you can stir it in.)
Cover very loosely (do not screw on lid), and leave out at room temperature overnight.
In the morning, enjoy with toppings, or screw on lid and refrigerate until you're ready to eat it. Keeps in the fridge for up to 5 days. Provides one VERY big meal or two smaller ones. (Sometimes, I just eat my breakfast leftovers with my lunch.)
