Shepherd'S Pie - Make-Ahead, Freeze Ahead, Oamc - cooking recipe

Ingredients

Base
6 lbs ground beef (comes in this quantity at most wholesale clubs)
2 medium onions, chopped
3 cups catsup
4 tablespoons mustard
6 tablespoons wine vinegar
3 teaspoons salt
6 teaspoons Worcestershire sauce
Middle
3 cups frozen green beans
3 cups frozen corn
Top
7 -10 lbs potatoes, cooked and mashed according to preferred method, try crockpot recipe suggested in notes above

Preparation

In large pot, brown beef with onions (I boil my beef, drain to reduce fat content, then add onions I've already sauteed).
Mix remaining BASE ingredients in large bowl.
Add beef and onions.
At this point I placed 1/3 of meat mixture in a cassarole dish, added 1 cup of each frozen veggie and layered on 1/3 of mashed potatoes.
Bake at 350F for an hour, or until heated through.
While dinner is baking up, I pack up the cooled remaining meat mixture dividing meat mixture left into 2 labeled gallon ziplock bags.
Divide remaining veggies into labled 2 qt freezer bags.
Divide remaining mashed potatoes into 2 labeled gallon freezer bags.
For convenience, I actually staple the bag of meat mixture, veggies and mashed potatoes together into 2 dinner groups to make it all easier to find in my freezer. Obviously, staple above the zip on the bag when stapling together. :-).
