I'm so glad to read this! I grew up in the Midwest, too, and loved braunschweiger with green onions and radishes on thin-sliced pumpernickel as a kid (my mom is Lithuania, raised in Germany). When I got to the East Coast, I couldn't find spreadable braunschweiger anymore and missed it so much!! I hate the sliceable liverwurst I was typically offered instead.... I eventually found one or two outlets, but nothing like the landsleberwurst Treasure Island used to sell (maybe still does?)....
