RE: Turkey burger?
These can really be a challenge, you want them cooked through, but still juicy. I find the best way is to make my own, and do it up almost like a meatloaf. Add chopped onion or green pepper, some mushrooms also help give moisture. Add salt, pepper, Worcestershire, the finely diced vegatables, and even sometimes an egg and some breadcrumbs.
I’ve grilled them, but a skillet works better.
They aren’t as good as a real beef burger, but they are healthier!
