I've included an easy recipe for a stir fry made with komatsuna (Japanese mustard spinach) and aburaage (Fried Tofu) in my Grocery Guide. Komatsuna is a vegetable high in calcium, so cooking it together with ingredients that contain protein or fat like soy products or dairy products will help absorb the calcium effectively in to your system. You can also just stir fry it with a good quality vegetable oil with a splash of soy sauce too.
