I've always made them the same way. I use 80/20 meat and make 1/3 lb patties. Put them on a cookie sheet or plate and drizzle a little worcestershire on them. Then I just crack some sea salt and pepper on top and grill them up, medium preferably.
I also like to grill some onion to go on them, and butter and toast the bun as well. Some pepper jack and whatever condiments you like. Mmm
