Drain, cut and place in buttered 1 1/2-quart baking dish.

Precook celery just a few seconds in microwave and add to onions.

Add tomato and squash to other vegetables.

Melt margarine in saucepan; remove from heat and mix in flour.

Pour over vegetables.

Sprinkle cracker crumbs on top and bake, uncovered, at 350° for 45 to 50 minutes or until vegetables test done. Mushrooms can be added, if desired.
