Cut your avocados in half, remove the seed, and brush them with some lime juice and olive oil. Place flesh-side down on your hot grill for about 5 to 7 minutes. Remove from the grill and fill the hole with your favorite salsa and top that with a little sour cream. Sprinkle the whole thing with some chopped cilantro, a good sprinkling of kosher salt and maybe another drizzle of lime juice. You can scoop it out with a spoon or serve with tortilla chips. Delicious!
