onegoal,
I beg your forgiveness for continuing the tangent (and thereby hijacking your thread).
Does anybody care to add anything to the discussion about maris ayin of parve cheese burgers (as in fleishig burgers w/ parve cheese)?
To reiterate my opinion; according to most poskim, (the Shach, and many acharonim explaining the R’ma) it would be assur to eat a hamburger with pareve cheese (or even a cold deli sandwich) in a public setting. The only way I see around it is to postulate that parve cheese is more prevalent today than almond milk was in the days of the R’ma, which I find unlikely. Having looked over the Badei Hashulchan, I see that this is his position (and it’s likely that I originally formulated my opinion a few years ago when learning the sefer).
One more thing to add; if the parve cheese is melted on to the meat (while on the fire), it would even be assur according to the Shach’s understanding of the R’ma. I have no idea how they make it, though.
