Preheat oven to 400 degrees. Grease a 9-inch tart or pie pan with cooking spray.
Unroll pie crust and arrange it on prepared pan. Gently press the crust into the bottom and sides of pan, trim any excess dough. Use a fork to prick the pie crust in several places (sides too). Brush on the beaten egg white on the dough. Bake the pie crust until slightly brown, about 10 minutes. Allow the crust to cool for 5-10 minutes.
In a nonstick skillet over medium-high heat, crumble in the sausage and cook until brown, about 5 minutes. Drain on a paper lined plate and set aside to slightly cool.
In a large bowl, beat the eggs, then add in the cream cheese, cheddar, and salt, mixing until smooth. Pour the mixture into the cooled crust and bake until set and the top is golden, about 25-30 minutes. Cool the tart for 10 minutes before removing from tart pan or cutting. Optional, garnish with diced green onion.
This recipe is customizable: you could swap different meats and cheeses. Great served with hot sauce or salsa.
