Heat a pan, cut tempeh into stripes and add to the pan together with sesame oil. Fry until the stripes turn brown and crispy. Remove tempeh.
Reduce the heat of the pan. Peel and slice a banana. Fry the banana slices in the same pan on both sides. This is a very quick process only fry them for 1 minute on every side, unless you like them very brownish.
Serve the tempeh and fried banana on top of wakame salad. Sprinkle on some scallion cut into rings.
