Mix all ingredients for cheese filling thoroughly. Cook manicotti pasta according to package directions. Drain; handling carefully, stuff each shell with 1/3-1/2 c. Of cheese filling. Cover the bottom of a 3 quart baking dish with a thin layer of spaghetti sauce. Lay shells side by side. Pour remaining sauce over stuffed shells. Sprinkle top with extra parmesan cheese. Bake ate 350 degrees F for 40 minutes or until hot & bubbly. Note: I find the manicotti pasta hard to stuff & use large shell shaped pasta instead. Walt Mm
