Ham and Cheese Brunch Squares

Oh, look! Another Easter recipe that thought it could escape! Breakfast is one of my top 3 meals of the day. Right after dessert and chocolate. This is Easter-y because I used leftover ham for it. Or it'd be good for an Easter brunch. Serves A-LOT. To serve even more, make in a cookie sheet, but keep an eye on the cooking times.

2-3 C shredded cheese
1 pkg shredded hash browns, thawed
8 oz cream cheese, softened
12 eggs (or 2 3/4 C liquid eggs)
1/2 tsp pepper
8 oz deli ham, coarsely chopped (or Easter leftovers, or sausage, or whatever breakfast meat you have around. Though, ham is my favorite. In case you make this for me some day.)
2 stalks green onion (optional.)
3 plum tomatoes (optional)

Preheat oven to 450 degrees. Spread hash browns into a greased 9x13" pan. Press gently into an even layer. Sprinkle half of the cheese evenly over the hash browns. Bake 13-15 minutes or until crust starts to brown and cheese is melted. Meanwhile, whisk cream cheese until smooth. Gradually add eggs and black pepper. Whisk until smooth{I kinda like the cream cheese to still be just a little chunky}. Slice green onions and cook with the ham over medium heat until hot. Sprinkle over the hash browns when they are done then pour the egg mixture over all. Bake 8-10 minutes longer until center is set. Top with remaining cheese and tomatoes.
