Heat oil in a heavy-bottomed pan to 350°F (175°C).
Season the squid rings and tentacles with salt and black pepper. Coat all the squids in all purpose flour and shake off any excess flour. Deep fry for 1 to 2 minutes until golden and set aside on a drying rack or paper towel.
In a wok, heat sesame oil on high heat and add ginger. Once the ginger is aromatic, add in the jalapenos, red onions and stir-fry for 30 seconds. Add the fried squids and toss for another 30 seconds.
Pour in dark and light soy sauce, rice wine vinegar, sriracha sauce and stir-fry for a minute until the sauce has coated the squids. Sprinkle over green onions and give a quick toss. Serve the squids in a bowl with garnish of sliced green onions.
