I believe its not permitted although whether the ban is actually applied seems to vary. In 2017 I asked at US customs in either JFK or Newark about it and was told it should be OK. On my next flight over I took in about 15-20 packs, declared it at customs, they x-rayed it and let it through. I had Expedition Foods veggie, beef and chicken meals. If I recall correctly Expedition Foods said they often send stuff to the US without problems. Best declare it though.
