Easy Cheesy Ground Beef Pie

This basic recipe has been on the Bisquick mix box for many years.  I've added potatoes, carrots and peas to include a good serving of vegetables.  It's a great winter comfort food.  Quick and easy and very good.
Ingredients
1 lb. very lean ground beef
1 large onion, chopped (about 1 cup)
1/2 large baked potato diced
1 large carrot sliced and steamed
1 cup of fresh peas steamed
1 cup of Cheddar cheese shredded
1/2 cup of Original Bisquick mix
1 cup of milk
2 eggs

Heat your oven to 400 degrees.  In a larger skillet, cook the beef and onion over medium heat until done.  Season to taste.  Also steam the veggies and dice a previously baked potato (I used one left over from last night).  In a small bowl, stir the Bisquick mix, milk and eggs.
Layer the ingredients as follows:

1. meat and onions,
2. baked potato,
3. peas and carrots,
4. shredded cheese,
5. pour Bisquick-milk-egg mixture over the top.

Bake for about 30 minutes or until a knife inserted in the center comes out clean.
