Trim ends off zucchini; cut in half lengthwise; scoop out centers, leaving 1/4" around skins. Combine zucchini centers in fry pan with all other ingredients except eggs and parsley. Saute 30 minutes. Place zucchini in baking dish; stuff with rice-vegetable mix; spoon any extra around zucchini; cover with foil. Bake for 20 minutes at 350 degrees. Prick holes in foil for steam to escape. Beat together eggs and parsley; pour over stuffed zucchini; recover and continue cooking 10 more minutes.
