Ham 'n' Cheese Pasta

Velveeta isn't my favorite, but since I tend to be a more picky eater than others I can see how normal people would enjoy this dish so I thought I would share it.

Ham 'n' Cheese Pasta8 oz. uncooked pasta shells
1 lb. process cheese (Velveeta), cubed
1/2 cup milk
2 Tbs. ketchup
1 Tbs. horseradish
2 cups cubed fully cooked ham
1 pkg. (8 oz.) frozen peas, thawed
-------
Cook pasta according to package directions. Meanwhile, in a microwave-safe bowl, combine cheese and milk. Cover and microwave on high for 2 minutes; stir. Heat 1-2 minutes longer or until smooth, stirring twice. Stir in ketchup and horseradish until blended.
Drain pasta and place in a bowl. Stir in the ham, peas and cheese sauce. Transfer to a greased 2-qt. baking dish. Cover and bake at 350° for 30-35 minutes or until bubbly.
