Cut about 1/3 of the tofu off and save the rest for later. Put it in the blender and blend until its liquid. (Actually, buying liquid tofu would make more sense but when I made this drink I used firm tofu because it was all I had.) Add the peaches gradually along with the juice and blend until smooth and creamy. I recommend refrigerating this before serving because warm smoothies are not that great. This is great for anytime and it takes only minutes to make. Enjoy!
