Cook the chicken and noodles first at the same time. Once noodles are done–rinse in cold water and set aside (it keeps them from sticking together). Combine evaporated milk (don’t use fat-free version) and Ranch dressing in a 3 quart heavy saucepan. Heat over low heat, stirring frequently until dry ingredients are dissolved. Stir in chicken and pepper. Simmer, uncovered, 25 minutes (don’t do any less), stirring frequently. Layer half of lasagna noodles, poultry sauce, and cheese in well-buttered 9×13 pan. Repeat layers again. Bake at 350 for 35-40 minutes or until hot and bubbly.
