Blend pasta sauce and peppers in blender until smooth. Combine egg, ricotta, 1-1/4 cups mozzarella, spinach, 1/4 cup Parmesan and nutmeg.
Cook lasagna noodles as directed on package, omitting salt. Meanwhile, heat oil in large nonstick skillet on medium heat. Add onions; cook and stir 5 min. or until crisp-tender. Stir in mushrooms; cook 10 min. or until tender and browned, stirring frequently.
Spread 3/4 cup sauce onto bottom of 13x9-inch baking dish; top with layers of 3 lasagna noodles, 1/3 each of the ricotta and mushroom mixtures, and 3/4 cup sauce. Repeat layers twice. Top with remaining noodles, sauce, mozzarella and Parmesan. Cover with foil sprayed with cooking spray.
Bake 1 hour or until heated through, uncovering after 45 min. Let stand 15 min. before cutting to serve.
Serve with smart sides, such as your favorite steamed vegetable and a crisp mixed green side salad tossed with your favorite KRAFT Lite Dressing.
Lasagna can be assembled ahead of time. Refrigerate until ready to bake as directed.
