Toast the baguette halves until golden brown. Drizzle a half teaspoon of olive oil over each piece of toast. Rub the crusty top of each piece of bread with the raw clove of garlic.
Place half of each thinly sliced avocado on each baguette half. Sprinkle the avocado generously with salt and a squeeze of fresh lemon juice. Use a fork and smash the avocado directly into the baguette.
Top the smashed avocado with the smoked salmon, radish slices, a sprinkle of fresh chives and a half teaspoon of olive oil drizzled on top. Serve immediately.
