Preheat oven to 425 degrees F. Cook bacon according to package directions; cool slightly and crumble or chop bacon. Set aside. Place tomatoes in a small bowl. Add enough boiling water to cover; let stand for 5 minutes. Drain tomatoes, discarding the liquid. Finely chop tomatoes. Set aside.
In a medium bowl stir together flours, baking powder, salt, and cream of tartar. Stir in green onion tops. Using a pastry blender, cut in vegetable oil spread and butter until mixture resembles coarse crumbs. Stir in crumbled bacon and chopped tomatoes. Make a well in the center of the flour mixture. Add milk all at once; stir just until dough clings together.
Turn out dough onto a lightly floured surface. Knead by folding and gently pressing dough for four to six strokes or until nearly smooth. Roll dough into an 8-inch square. Cut into 1-inch-wide strips; cut each strip in half crosswise. If desired, twist each strip.
Place strips 1 inch apart on an ungreased baking sheet. Coat with cooking spray; sprinkle with Parmesan cheese. Bake for 8 to 10 minutes or until tops are golden brown. Serve warm.
