Preheat the oven to 500 degrees.
Spray a baking dish with canola non-stick cooking spray.
On a piece of wax paper:
Mix
1 tablespoon kosher salt
1 tablespoon black pepper
2 teaspoons garlic powder

Rinse and pat the loin dry.
Roll a 2 pound tenderloin in the spices to coat.
Place loin in baking dish and place uncovered in the HOT oven. Leave oven on approximately 10 minutes, then turn off.

DO NOT OPEN THE OVEN DOOR for 4 hours or more. The residual heat from the oven will cook the loin to perfection without drying it out. Slice in 1/2 inch rounds and serve.

Serves 6-8 people.

Note: (Kroger will sell the loin already cut in half for easier backing). I actually grind course house seasoning over the sides of mine, turning it in the pan,  instead of rolling it on the wax paper.
