Rub garlic clove on each slice of hot baguette. This will add a perfect light garlic essence without being "in your face" or oily. This technique is actually one of my favorites to use with crostinis or toasted sandwiches.
Mix together tomato, avocado, cilantro, lime juice, and olive oil. Season to taste with salt and pepper.
Scoop spoonfuls of the tomato/avocado mixture onto the garlic rubbed crostinis.
