I'm not familiar with this Rashba but I do concur that this how inderstand
the Rambam in Hil. Shabbos 9:6 "klalo shell davar..."

FWIW RMF/IM asserts that microwaves are derech bishul based off of a Rashi
in Mas. Shabbos that says Hammah is NOT derech bishul.

[I'm sure RDE can provide the citation in full. <Smile>]


Further tangentially, I have argued with "liberals" who claimed that bishul
via electricity is not real bishul. One issue is that it would create a
michshol that anything cooked electically could not be re-heated w/o chancing
a d'oraisso. Taken a step further, any cooked food would be a s'feiq mevushal-
lest it was first only cooked electrically.

Also it would preclude broiling by means of electicity EG for livers.
