1. Arrange biscuits, with sides touching, in 3 rows of 4 biscuits on a lightly floured surface. Let stand 30 to 45 minutes or until biscuits are thawed but cool to the touch.
2. Preheat oven to 375°. Sprinkle biscuits lightly with flour. Press edges together, and pat to form a 10- x 12-inch rectangle of dough; spread dough with pimiento cheese.
3. Roll up, starting at one long end; cut into 12 (1-inch-thick) slices. Place 1 slice into each muffin cup of a lightly greased 12-cup muffin pan.
4. Bake at 375° for 20 to 25 minutes or until golden. Let cool in pan on a wire rack 5 minutes; remove from pan, and serve immediately.
