Ready-to-drink beverages comprise a significant amount of complete protein per 8 fluid-ounce serving, the proteins derived from a plant protein blend comprising a legume protein, a whole grain protein, and a dairy or wheat protein. Other components added include a sweetening component, a flavor component, hydrocolloids, and optionally maltodextrin to produce a ready-to-drink beverage with no visible sedimentation and good taste and mouthfeel. The components are subjected to a high temperature treatment step, followed by a homogenizing step. Formulations provide for source of high quality, complete protein.
