I had an overripe banana and absolute no desire to turn the oven on for muffins or bread. It was in a bowl right next to the package of pre-made tostadas and I got this wild idea that it just might work. It did.
I crushed the banana with a fork and spread it on the tostada. Then I sprinkled some Tajín on it, though you could just use some chile powder and salt. Then I chopped up about two inches from a green onion and sprinkled on top.
I liked the flavor mix the tart and sweet and salty, but I do think the banana might be even better spread on two tostadas. A bit more salt and crunch ratio would make it a bit more tasty. Next time I have overripe bananas, I will try it again. It was a nice breakfast and would make a good snack.
