Preheat the oven to 350º Fahrenheit.
In a medium bowl, combine the ham, cheese, mayonnaise, dill weed, and salt and stir to mix well.
I like to add a pinch of dill and salt, you could add a pinch of thyme too.
Unroll the crescent roll dough and separate it into 8 triangles, keeping the matching triangles together.
Lay 4 of the dough triangles on a baking sheet. Spoon ½ cup of the ham mixture onto each of the 4 triangles. Place the matching triangles of dough on top and pinch the edges together to seal them tightly.
Bake for 8 to 10 minutes, until the tops of the turnovers are golden brown.
Serve hot.
