Notes: Eligio Hernández of Mountain View, California, often ate this make-it-yourself guacamole for a casual lunch or snack in Mexico, where he grew up. Its simple presentation also makes it a stunning first course for a meal.
Cut avocado in half lengthwise; remove pit. Set each half, cut side up, on a salad plate. Spoon 1 tablespoon salsa into each cavity. Set lime halves and tortillas alongside.
To eat, squeeze lime halves over avocado and sprinkle with salt to taste. With a fork or a spoon, mash avocado slightly with salsa in peel, then spoon mixture onto tortillas.
