The ingredient list is slim and all available at Harris Teeter or Walmart, but miso paste will likely require a special stop at an Asian market or the international aisle hunt if your local chain doesn't stock it well—a real friction for a five-minute condiment. At roughly 60 cents per serving for tofu, miso, and oil, this is genuinely cheap, though the output is a small amount of mayo-like spread that works best as a condiment rather than a meal component. The five-minute claim is honest if you have an immersion blender or food processor ready; without one, you are looking at ten minutes of vigorous whisking. This keeps well in the fridge for a week, making it a smart prep-ahead sauce for grain bowls or sandwiches, but it is not a weeknight entree on its own.
