Soya is EPIC!

So today i discovered that 100g of soya chunks hydrated contains 51g of protein. You would have to eat almost 200g of chicken to get near that amount. Also, the cost of 100g Soya is about 35p compared to 95p for the same weight in chicken. Ive got to do a little research to find out if the body utilises all the protein in the soya.
