How to Make It
Place squash, onion, and carrot in a vegetable steamer over boiling water; cover and steam 12 to 15 minutes or until vegetables are tender. Combine steamed vegetables, cheese, and next 5 ingredients in a medium bowl; stir well. Spoon mixture into a shallow 2-quart casserole coated with cooking spray.
Combine breadcrumbs and remaining ingredients in a small bowl; stir well. Sprinkle over squash mixture. Bake, uncovered, at 350° for 25 to 30 minutes or until thoroughly heated.
