This is a great point, and it's something that the Founding Fathers really just kicked the can down the road for succeeding generations to find out. The executive doing so is technically in violation of the Take Care Clause ("shall take Care that the Laws be faithfully executed"), and SOME judicial proceedings since then have found that the Executive can't use under-spending to deny or delay a congressional act or program (Train v.
