I have lived communally using an outdoor kitchen that didn't have a regular
oven (toaster oven-->check), and it would have been nice to know about this back then.
This
sourdough is easy and cheap...The starter I keep going is mixed in with flour,
water, salt, dried garlic, and herbs(I do half white/whole wheat) and is let rise. More flour is kneaded in and spread out to about 3/4 inch thick to let rise a little more. This is chopped into toaster sized biscuits and cooked stove-top in a pan about 5 minutes each side. As needed I cut them in half and toast to perfection (inside isn't fully cooked just on pan).
Sourdough is supposed to be good for digestion etc and I have read this is partly due to gluten breakdown. It's tasty! Once a culture is going it is hard to kill and can be kept indefinitely only requiring flour and water.
