Dice the ham into small pieces.

Mince the onion and sauté in butter and olive oil until softened.

In a bowl, combine the diced ham, Mexican cheese mix, grainy mustard, sautéed onion, lemon pepper, and salt.

Mix the ingredients thoroughly until well combined.

Fill each kolache dough portion with the ham and cheese mixture.

Let the filled kolaches rise for one hour.

Spray the kolaches with water and sprinkle with coarse sea salt.

Bake until golden brown and the filling is heated through.
