1. Preheat the oven to 400°f.
2. Slice half a french bread on the diagonal into ½" rounds and place on a baking sheet.
3. Toast the sliced bread in the oven for 3 minutes, then flip each piece over and toast an additional 3 minutes.
4. Remove the toasted bread from the oven and immediately rub with a clove of garlic. (it works best to first cut a small tip off the garlic clove so that the oils will seep out).
5. Brush the tops of the garlic-rubbed toasts with olive oil and set aside.
6. In a large bowl, combine 2 medium chopped tomatoes, 2 medium chopped avocado, 1/3 cup finely chopped onion, 1/4 cup chopped cilantro, 2 tbsp lime juice, 1/2 tsp salt and 1/4 tsp black pepper. mix together gently making sure the avocado is well coated in the lime juice.
7. Spoon a portion of the mixture onto each of the garlic toasts and serve.
