Since you're not a big meat eater then you could always go the protein shake route. My suggestions is to add some veggies and fruits to the shake. Do at least 1 veggies with 1 fruit. Its add a little sweetness and a little crystal light for flavoring ain't bad either. This way it taste better and you're also getting some more nutritional value. There are a lot of other ways to get protein. Almonds & eggs are a good source.
