Preheat oven to 325 degrees. Place roast on broiler pan. Brush with olive oil. Cut small slits all over, just big enough to place a clove of garlic and sprig of basil in. Do this according to taste. ( I use a lot ) If you want, you can sprinkle dried basil on the roast instead. If you can tolerate Rosemary, it is delicious, also. Rosemary is very pungent, so don't try it unless Matia says it's ok for you. Sprinkle roast all over with salt and pepper. Place thermometer in center of roast. Bake uncovered, until thermometer reaches 170 degrees. Let stand for 10 minutes before slicing.
