Cook frozen broccoli florets in microwave until crisp-tender (I cooked mine for about 2 minutes, stirred, and then cooked for another 1 minute).
Meanwhile, in a large bowl, stir together soup, milk, soy sauce, and fried onions.
Add cooked broccoli and stir to combine.
Pour mixture into 1 ½ quart baking dish.
In a small bowl, combine crushed crackers and melted butter. Sprinkle buttered crumbs on top of casserole.
Bake at 350 degrees F for about 25-30 minutes, or until hot and bubbling.
