Method:
Preheat the oven to 350°F. Combine flour, salt, and yeast. Mix in warm milk and oil.
Knead for 10 minutes and then divide dough into two equal pieces.
On a floured surface, roll out to one 12 x 18-inch rectangle and spread with tomato paste.
Combine onion, pineapple, ham, cheese, and parsley and sprinkle over the tomato paste.
Roll rectangle lengthwise in jelly-roll style, cut into 16 slices each and transfer to a parchment paper-lined baking sheet. Bake until golden brown and cooked through, about 25 minutes.
