Tunafish!

Ok so I'm on a new quest to eat a lot of lovely, filling, protein rich food; and today I discovered that 100g of tinned tuna fish has a phenomenal 25g of protein with only 105 calories. I've been a vegetarian for 7 years now but this is seriously making me consider turning pescatarian (I believe is the word) or at least maybe eating tuna.

Does anyone know of any really low calorie high protein foods like this that are vegetarian? I eat already eat quorn (which is about 13g per hundred of protein with 95 calories) but this is quite expensive so I don't want to eat anymore of it than I already do. Apart from this I eat nonfat yoghurt, skimmed milk, eggs and extra low fat soft cheese for protein.

I'm really conflicted on this issue, I'm hoping someone can convince me to stay veggie though!

Here is a link to a site that discusses, in considerable detail, the damage caused by overfishing and poor fishing practices. It includes a guide to which seafoods are sustainable and which should be avoided.

Here's pretty much the same info (with mercury info as well - how much tuna you can eat per week per body weight, etc):

Either use that link for the info or if you don't trust me you can go to NRDC.org and search for wallet cards :)

i'm a pescatarian, and eat fish about once a week. there's a little deli near me that makes a great tuna salad with lots of veggies and little mayo. so when i'm in a crunch, i'll grab that as lunch, but otherwise i try to stay away from the tuna.

if you want more protein, but don't want to eat fish, try fage yogurt. the 2% kind has 17 grams of protein for 130 calories, which is pretty good. i usually add 1/2 a cup of kashi go lean crunch or just a tablespoon of jam in it.
