from an interview on krishnatemple.com (undated but possibly 1989): Mukunda: You've been a vegetarian for years, George. Have you had any difficulties maintaining it? George: No. Actually, I wised up and made sure I had dal bean soup or something every day. Actually, lentils are one of the cheapest things, but they give you A-l protein. People are simply screwing up when they go out and buy beef steak, which is killing them with cancer and heart troubles. The stuff costs a fortune too. You could feed a thousand people with lentil soup for the cost of half a dozen filets. Does that make sense?

Joshua Green, the author of "Here Comes the Sun: The Spiritual and Musical Journey of George Harrison", attended several recording sessions with George. He said there would always be 'huge trays of vegetarian food' in the studio.
