Transfer the tofu to a 12 inch skillet, and add 1 cup of liquid (either water, broth, or a mixture, depending on how salty you want the tofu, I suggest tasting the tofu before adding any broth so it doesn't get too salty) and stir to combine. Bring to a simmer and then simmer until the liquid is mostly reduced. About 5 - 10 minutes or so. Taste and adjust for seasoning.
