Use day-old cold rice if you can; freshly cooked rice spread on a tray and chilled 15 minutes works too.
Crumble the tofu into a hot oiled skillet or wok and cook 7 minutes until golden; push to the side.
Add the remaining oil, garlic and white parts of the green onions for 30 seconds, then the frozen vegetables for 2 minutes.
Add the rice and drained pineapple and stir-fry 4-5 minutes over high heat, pressing the rice against the pan to crisp.
Drizzle with tamari and sesame oil, toss well, and finish with green onion tops.
