Sometimes when you are just too tired to cook an elaborated dinner and the thought of getting take-out (which I never do) just is not attractive (to the wallet, the wait time, or nutrition-wise), my default is usually a plate of greens (Chinese broccoli is my favorite) and perhaps a dish of steamed silken tofu.
Tofu is usually sold in a boxed carton in any Asian supermarkets or most American supermarkets nowadays. Just be sure to get the silken kind and not the firm one, since the latter is mainly in a stir fry dish. I just slide the block of tofu onto a plate, drizzle some olive oil, scatter some diced scallions and cilantro, and steam it along with my rice in the rice-cooker. A “one pot meal” you can say. Then, to finish it off, I like to dress it with a splash of soy sauce or teriyaki sauce.
Dinner is served.
