In a saucepan, cook potatoes until tender in enough lightly salted, boiling water to cover, about 20 to 30 minuters. Cool slightly. Slice the potatoes and place in large bowl.
In a separate bowl combine cottage cheese, sour cream, green onions, parsley, dillweed, and salt. Add to the potatoes. Spoon the potato mixture into a lightly greased baking dish. Sprinkle with cheddar cheese and Monterey Jack cheese. Bake at 350° F or 30 minutes, or until bubbly.
