Vegetarian Note: There is Protein in almost everything

If you try to replace meat protein with beans gram for gram, you will just end up farting all day. 

When I tell someone I'm a vegetarian so often the question they fire back is, Where do you get your protein? 

Well there's protein in everything. All the nutrients you need are in the Earth. 

The cow gets its nutrition from the plants then humans eat the cow, the vegetarian just bypasses the cow.
