I had buns left over from my salmon cake recipe that I needed to use up before they went bad, so while at Trader Joe's I bought their frozen 4 patty veggie burgers. I took one patty to work still frozen, popped it in the microwave for 2 minutes, placed it on a bun with mustard and hot peppers and was really impressed with the easiness of it all. This is a great quick little sandwich to make when you are in a rush but need something to fill you up. The patties have carrots, onions, celery, bread crumbs, and wheat as just some of the ingredients. Its not overwhelming in flavor, you definitely need a condiment on it but that's what always makes burgers fun, what you add to them.
I made the burger for lunch today just to try it with other condiments. I poured worcestershire sauce on the patty and placed marinated artichokes on top, combined with a fresh salad I feel full but not heavy.
If you get a chance to try, I highly recommend!
