Cut each chicken breast in half horizontally. Place chicken between 2 sheets of heavy-duty plastic wrap; flatten to 1/4-inch thickness, using a rolling pin or the flat side of a meat mallet.
Sprinkle chicken evenly with salt and pepper; lightly dredge in breadcrumbs.
Cook half of chicken in 1 Tbsp. hot oil in a large nonstick skillet over medium-high heat 2 minutes on each side or until golden brown and done. Remove chicken to a serving platter, and cover with aluminum foil. Repeat procedure with remaining chicken and 1 Tbsp. olive oil.
Add broth and lemon juice to skillet, and cook, stirring to loosen particles from bottom of skillet, until sauce is slightly thickened. Remove from heat; add butter and parsley, stirring until butter melts. Pour sauce over chicken, and serve over warm noodles.
