Tater Tots and Corned Beef? Possible?

I've been thinking about this recipe for weeks now. I've been scouring the Internet and have been trying to come up with a recipe that includes both Tater Tots and corned beef. I am doing Sunday Brunch at church this weekend and am working with a St. Patrick's Day theme--table covers, napkins and flower arrangements all in an assortment of greens. I've settled on a Spinach and Strawberry Salad with Gorgonzola crumbles and toasted pecans lightly dressed with a honey balsamic vinagrette, but am still stumbling with the main dish. My intention is to use this recipe, which I've cobbled together from a number of recipes, and substitute diced corned beef in a couple of the casseroles (I am making 8--3 corned beef, 3 sausage, and 2 vegetarian).

If you've ever made this type of casserole and used corned beef I would love to hear from you!

Note from Sunday Brunch: Although I liked the corned beef version, the pork sausage recipe is much tastier!

Overnight Breakfast Tater Tot Casserole

1 pound bulk pork sausage

2 tablespoons olive oil

1 cup chopped onion

1 cup chopped green pepper

8 eggs

2 cups half and half

1 tsp. dry mustard

1 tsp. salt

1 32 ounce package tater tots

2 cups grated cheddar cheese

Baking spray

Brown sausage in olive oil until no longer pink. Add onion and green pepper and sauté until vegetables are wilted. Drain off extra oil.

Spray 9 x 13 casserole pan with olive oil baking spray. Spread sausage mixture in bottom of pan. Allow to cool.

Sprinkle with 1 cup cheddar cheese. Spread tater tots over sausage and cheese and sprinkle with remaining 1 cup of cheese.

Combine eggs, half and half, mustard and salt in blender. Blend until smooth about 1-2 minutes. 

Pour egg mixture over tater tots.*

Bake uncovered at 350 degrees for about 45 minutes or until eggs are set and tater tots have browned.

*If you are making this dish overnight, you may  cover the sausage, cheese and tater tot mixture with tin foil and store in the refrigerator overnight. Make the egg and milk mixture in the morning and pour over the casserole and bake as directed.
