How to Make It
Wash squash; cut in half lengthwise. Remove and discard seeds. Place squash, cut sides down, in a 13- x 9- x 2-inch baking dish coated with cooking spray. Bake at 350° for 45 minutes or until tender; let cool slightly. Using a fork, remove spaghetti-like strands from squash; discard shells. Place strands on a platter; set aside, and keep warm.
Coat a saucepan with cooking spray; add oil. Place over medium-high heat until hot. Add leek; saute 3 minutes or until tender. Add beans and tomato; cook over medium heat 5 minutes. Stir in olives and next 3 ingredients; cook until thoroughly heated. Spoon bean mixture over squash. Garnish with fresh celery leaves, if desired.
