Beef-Vegetable Pie (WW)

Made this the other night again when I didn't really have a plan I was just searching for a recipe with ingredients I had on hand. I again changed the recipe from the original, based on what my family would like and on reading the reviews. Does anyone read the reviews on recipes when you get them online? I find them very helpful. Just a helpful hint if you don't do it already!

Beef-Vegetable Pie
1 pound(s) raw lean ground beef
1 packet of onion soup mix
1/2 tsp table salt
1/4 tsp black pepper
2 cup(s) dry potato flakes
1 1/2 cup(s) low fat milk
10 oz frozen mixed vegetables (or a combination of fresh veggies, this is what I did - carrots, corn, peas, and broccoli)
1/2 cup(s) low-fat shredded cheddar cheese
Instructions
1.Preheat oven to 450°F. Pat beef into a 9-inch pie plate and sprinkle with 1/4 teaspoon each salt and pepper, and the onion soup packet. Cook until beef browns, about 18-20 minutes, and remove from oven; set aside and preheat broiler.

2.Meanwhile, combine potatoes and milk in a microwavable bowl. Cover with plastic wrap and turn back a corner of plastic to allow steam to escape. Microwave until hot, about 1 to 2 minutes; whisk with a fork until smooth and set aside. Microwave vegetables according to package directions; mix vegetables and remaining 1/4 teaspoon of salt into potatoes.

3.Pour off any accumulated juices from beef. Pat potato mixture into meat crust and sprinkle with cheese. Broil 4 inches from heating element until cheese is melted, about 2 to 3 minutes. Slice into 6 pieces and serve.
