How do I cut out the vein/tendon from a chicken breast tendorloin? I like to cook grilled chicken sometimes to go in salads. The problem I always have is that in the chicken breast tendorloins I buy, there is always a tendon or vein or something. It's white when uncooked and is extremely tough.

At first I tried not messing with it, but many bites of the chicken I had was basically not capable of being chewed up. 

Now, I try to cut it out, but it's extremely difficult to cut out because it appears to run through the entire tenderloin. Last night I tried cutting it out and what I ended up with was basically tearing the chicken apart into lots of small chunks. In the end it still tasted good, but I'd really prefer an easier method. 

What's the easiest method of cutting out that vein/tendon thing from the tenderloins?
Cooking For Engineers has a pretty good description. He writes it better than I can, so I'll just quote him. I've used the second method he describes, but after watching the video below, the other looks much easier...


  The breast halves should each have a flap of meat called the chicken tenderloin (or chicken tenders or strips). Lifting the tenderloin should reveal a white tendon. I recommend two ways to trim off this tough tendon. The most popular method is to grab the tendon with your fingers and pull on it while scraping with your knife to release the tendon from the breast. Continue to lift and scrape until the tendon is completely removed. Alternatively, you can use a sharp boning knife and slice along both sides of the tendon (without slicing through the tendon). Then lift any part of the tendon that has been separated from the breast and use your boning knife the cut any parts where the tendon has not cleanly separated from the meat.
