I wasn't thinking of the meat as the substitute. I was more thinking of combining the different plant foods. For example lentils has many of the amino acids missing in most veggis. However, here lentils and beans for a long time have been considered poor peoples food and thus avoided. Now with the meat scandals, BSF, hormons etc. even chi-chi restaurants start serving fancy lentil dishes again. I would say unless you live way up north, there is no real need for meat as a food source. I do not mind people eating a little meat, if they do it consciously and even with a little gratefulness to the animal that gave its life so that the human can live, or better in most cases just tickle his taste buds.
