Heat pasta sauce to a minimum of 155° while pasta is cooking. Do not boil, just gently simmer.

Cool farfalle al dente. Drain.

Heat butter in a medium sized saute pan. Sear ham on both sides for approximately 1 minute, or until ham is thoroughly heated.

In a large mixing bowl or saucepot, combine farfalle, pasta sauce, cheese, and ham. Mix together. (Save a little cheese to top pasta before baking and a little cheese for garnish)

Transfer to a casserole dish. Sprinkle some cheese atop. Bake uncovered at 400° for approximately 5 minutes or until cheese is bubbly.
