Preheat the oven to 375 degrees F (190 degrees C).

Mix cream cheese, bacon, Parmesan cheese, onion, parsley, and milk together in a bowl.

Separate each can of dough into 8 triangles; cut each triangle lengthwise in half. Spread each dough triangle with 1 generous teaspoon cream cheese mixture; roll up, starting at short side of triangle. Place, point-side down, on baking sheet.

Bake in the preheated oven for 12 to 15 minutes or until golden brown. Serve warm.
