We loved this roast with gravy. We used Knorr Classic Brown Gravy Mix prepared according to package directions.
Preheat oven to 425°. Sprinkle pork with salt and pepper. Tie pork with kitchen string, securing at 2-inch intervals.
Cook pork, fat side down, in 3 Tbsp. hot oil in a stainless-steel skillet over medium-high heat 3 to 5 minutes on each side or until golden brown. Place, fat side up, on a wire rack in an aluminum foil-lined roasting pan. Remove kitchen string; make 5 (1/2-inch-deep) cuts in pork.
Stir together sage, next 3 ingredients, and remaining 2 Tbsp. oil. Stuff herb mixture into slits in pork.
Bake at 425° for 30 to 40 minutes or until a meat thermometer inserted into thickest portion registers 150°. Let stand 10 minutes before serving.
