That actually sounds like a decent pair of stir fries: Lettuce + jalapeno + banana Banana + spinach + jalapeno + cilantro Banana is a bit of an odd ingredient here, but the key would be to cook it separately and very lightly, so it's more like a plantain. A good technique while you're learning how to cook is if some combination of ingredients sounds dodgy, cook them separately first, then put small amounts together and see if it works as a dish. Sometimes it helps to adjust the ratio or add some seasoning.
