½ small onion, small dice
1/3 med red pepper, diced
½ cup diced kielbasa sausage

9 large eggs
¾ tsp kosher salt

Heat oven to 375F. Butter the insides of a 7-inch spring form pan. Line the bottom and sides with parchment paper.
Squeeze any excess moisture from hash browns. In a large bowl, combine hash browns with butter, onion, red pepper, sausage,1 cup of the cheddar, salt and pepper. Whisk eggs and add to hash brown mixture; fold to combine.
