Give the rice some time to cook as you prepare all the vegetables. Drain the tofu and squeeze it gently to release some of the water. Slice it in half, into two square slabs, and slice it into bite-sized strips.
Cook the rice. Rinse the rice in a mesh colander and then cook it in a rice cooker with 2½ cups water, according to your manufacturer's instructions and the volumes given above. Alternatively, you can cook it on the stove. Bring 2½ cups of water to a boil over high heat. Rinse the rice, then add it to the pan. Reduce heat to a simmer, cover and let it cook until all water is absorbed (35-40 minutes). If it gets too dry, add a splash or more of water as necessary. Fluff with a fork and allow to cool for 10 minutes.
