COOK pasta in large saucepan as directed on package. Meanwhile, combine cracker crumbs, Parmesan cheese and oregano in pie plate. Lightly beat egg white in separate pie plate. Dip chicken in egg white, then roll in crumb mixture until evenly coated. Set aside.
SPRAY large nonstick skillet with cooking spray. Heat on medium heat. Add chicken; cook 5 min. on each side or until cooked through (170ºF). Spoon 1 cup of the pasta sauce over chicken; top with mozzarella cheese. Cover skillet with lid. Reduce heat to low; simmer 3 min. or until sauce is hot and cheese is melted.
MEANWHILE, drain pasta; return to pan. Add remaining 1 cup pasta sauce; toss to coat. Cook on medium heat 2 min. or until heated through, stirring occasionally. Spoon onto serving plates; top with the chicken.
