Stated plan

Deliver check with the bishop to clear the e-file, then win the queen with the rook.

Reasoning

Black's bishop is blocking its own rook on e4 from attacking the queen on e2. Playing Be3-g1+ gives check to the king on h2 while simultaneously clearing the e-file. White has no way to defend both the check and the queen: after Kxg1 or Kh1, Rxe2 wins the queen outright.
