I've had these sandwiches for years -- very effective in boosting immunity. I keep the meat and cheese sandwiches separate; raw yellow onion goes wonderfully with both; bread can also be rye, and substitute butter for mayo on the cheese sandwiches. No mustard, I don't care for it. Sometimes, on roast beef, I'll mix horseradish with sour cream. Onions, though, are key. Once, when I had serious problems eating, I could eat only liverwurst on rye with raw onion. I think it saved my life. (Thanks to commenter Khalid about horseradish cheese; going to look for it!)
