So pe means on...
Why is it "pe orez" and not "cu orez"? Is that an exception or is there any rule to differentiate pe and cu?
It depends, but here it should be "cu"
"Cu" means "with" if I recall.
Cum adica ea mananca curcan PE orez?!
In fine dining everything is "on" (pe). Normally we would say "with" (cu).
