Heat the olive oil in a medium sized frying pan over medium heat. Add the bacon and grill, flipping every few minutes, until they are nice and crispy. Remove the bacon from the pan and reserve the drippings inside the pan. Break the bacon into roughly 2-inch squares and set them aside.

In a medium-sized bowl, mix together the cucumbers, tomatoes and cilantro. Then gently stir in the bacon and avocado, taking care not to crush the avocado chunks as they are very soft. Drizzle the drippings from the pan over the salad. Add salt and pepper to taste.
