Brush the inside of the avocado halves with the olive oil. Place the avocado halves cut-side down on the grill for 1 minute and 30 seconds. Turn the avocado halves 90 degrees to get cross grill marks and cook for another 1 minute and 30 seconds.
Remove from the grill and season with salt and pepper. Put about 1 heaping tablespoon of salsa into the center well of each avocado half. Garnish with hot sauce and serve.
