What's for Dinner?

This is definitely something different. I loved the broccoli on top with the cheese but I could take or leave the meat and onion part underneath. My 10 year old gobbled it up though! Makes 8 servings.

Ingredients

2 (16 ounce) packages frozen broccoli
2 pounds ground beef
1 (8 ounce) package fresh mushrooms
1 large onion, chopped
salt to taste
ground black pepper to taste
2 (10.75 ounce) cans condensed cream of celery soup
1 (16 ounce) container sour cream
1 (16 ounce) package shredded Monterey Jack cheese

Directions

Preheat oven to 350 degrees F (175 degrees C). Prepare the broccoli according to package directions.
In a skillet over medium heat, mix the ground beef, mushrooms, and onion. Cook until beef is evenly brown; drain grease. Season with salt and pepper, and mix in cream of celery soup and sour cream. Continue cooking until heated through. Transfer to a medium baking dish, and evenly layer with broccoli. Top with cheese.
Bake 1 hour in the preheated oven, until bubbly and lightly brown.
