Broccoli Puff

Ingredients

1 (10 oz.) pkg. frozen chopped broccoli
1 can Cream of Mushroom soup
1/2 c. grated Cheddar cheese
1/4 c. milk
1/2 c. mayonnaise (if you can access Dukes mayonnaise- use it! Any other brand will work ok, but not as yummy...but for the love of all that is good and true, DO NOT USE Hellmann's or any other "dressing" type mayo)
1 egg, beaten
1 tbsp. butter, melted
1/4 c. bread crumbs
