shamburger
n.— «Shamburgers, a high-protein alternative to meat, can be made ahead, individually covered in plastic wrap and frozen until used. When needed, simply unthaw a Shamburger, and it will be ready to fry or to throw on a grill 5 minutes before the real hamburgers have finished cooking.» —“Shamburgers offer tasty, sage choice” by Judith Olney Washington Times (District of Columbia) Apr. 8, 1992.
