This recipe is Joel's mom's, and it lured me away from my freshman-year foray into vegetarianism. It's quite good, and Joel makes it now. He does a couple things a little differently, like (when we find it) using a mixture of ground beef, veal and pork instead of just beef, and he definitely uses more Worcestershire sauce, but essentially, it's the same excellent recipe.
2 lbs. ground meat (preferably beef, pork and veal)
About 1/2 c. chopped red onion
1 tsp. sea salt
1 tsp. pepper
Several long glugs of Worcestershire sauce
1/2-1 c. breadcrumbs (or as much as it takes to make it feel "right")
Mix by hand in a large bowl, shape into a loaf, and place in an electric skillet. "Frost" the top with ketchup. Slice baby red potatoes in half and cover the rest of the skillet bottom with potatoes. Put the lid on, set the temp to 275-degrees F, and cook for 40 min. to 1 hour.
