I am soooo tired of hearing it. "How do you get protein?" "Where is your protein?" "Don't you need protein?"
The sources are so many. Just off the top of my head I can name these: whole grain bread, brown rice, all beans, lentils, peas, nuts, seeds, nut butters, soy, meat substitutes, veggie burgers, protein powder and the every versatile tofu.
I would love to walk up to those same people while they are eating a big mac and fries and ask them, "Where's the vegetables and fruit?" My husband would be quick to reply that fries are potatoes and potatoes are a vegetable. But that still leaves the fruit! : )
