I think that Kenji's series of pressure cooker recipes are probably my favorites of everything he did when he was doing The Food Lab section. Almost every recipe is fantastic and they are mostly pretty easy. If I had to pick my single favorite, it would probably be the pressure cooker chicken enchilads [0], although that one is on the higher end of the effort spectrum
