Green olives, whole dill pickles, beef jerky -- satisfying and high in salt. Or have a hot drink like tea or bullion. Avoid cheese or nuts
Getting adequate protein during the day helps a great deal. I aim for 88 grams/day or about the amount in 4 chicken drumsticks or 4 cans of tuna. If short and still hungry I sometimes have a protein shake (30g) made with water and 50% cream. Never a shake by itself though.
