Preheat oven to 425 degrees Fahrenheit (220 degrees Celsius). Cut the baguettes on an angle to create even slices, approximately eight slices per baguette, and place on a baking sheet (or two sheets, if necessary).

Slice the garlic cloves in half and rub each piece of bread with the garlic. Drizzle lightly with olive oil and bake in oven for about 10 minutes or until edges are just browning.

For the avocado dip, combine the chili paste and olive oil. Brush eight slices of toasted bread with the combination.

Toss the avocado with the lemon juice and let it rest in a separate bowl until ready to serve. Mix avocado with the chopped scallion and sprinkle generously with the flaked salt. Heap the mixture evenly on top of the chili-lined bread.

Cover another eight slices of toasted bread with the lox, and sprinkle with black pepper and capers.

For the bruschetta, mix together the sliced tomatoes with defrosted cubes and herbs. Arrange on the remaining eight slices of toasted bread and sprinkle with large-flaked salt.

Plate the crostini with one slice of each topping per plate.
