Preheat oven to 400°.
Slice baguette into ½ inch slices. Brush both sides with olive oil and place on a sheet pan in a 400° oven for 15 minutes, or until crisp. Set aside.
Toss tomatoes in a medium bowl with 2 tablespoons of olive oil, balsamic vinegar, sea salt and pepper.
Fold in leeks, peaches, avocado, and basil and toss to coat. Taste and adjust seasonings, adding more salt and pepper if needed.
Rub each toasted slice on one side with a halved garlic clove. Brush garlic-rubbed slices with olive oil. Top each slice generously with the bruschetta mix just before serving.
*Avocado can be replaced with quartered Buf Mozzarella Ciliegine balls, or a generous spread of goat cheese or cream cheese on each toasted slice before topping with bruschetta mix.
