In your mixer bowl, combine the first 7 ingredients and mix well.
Gradually add water until you get a uniform consistent dough.
Add the butter cubes and knead until everything is well combined.
On a floured surface knead your dough for 3-5 more minutes then roll into a rectangle.
Fold the dough in thirds, then in half and roll again into a rectangle.
Repeat the rolling and folding for 2 times.
Cover and let it rise for an hour or until doubled in size.
Take your dough out and cut into two equal parts.
Roll each part into a 1/4 inch thickness then cut into 8 equal squares.
Fill each square with half a slice of the deli meat and about 2 teaspoon cheese.
Fold the square to form a triangle pressing on the edges to seal.
Cover and let it rest for 20-30 minutes until you preheat your oven to 350F.
When ready to bake press to seal the edges again and brush lightly with beaten egg.
Bake for 10-12 minutes until golden brown.
Let it cool down on a cooling rack.
Serve and Enjoy!!**
