Step 1

For garlic chapons, preheat oven to 180C. Brush both sides of baguette slices with oil, then bake on an oven tray, turning once, until golden (5-10 minutes). Rub bread with cut side of garlic, season to taste and cool. Chapons will keep in an airtight container for up to 2 days.

Step 2

Combine crab, mayonnaise, shallot and herbs in a bowl, and season to taste.

Step 3

Layer lettuce and avocado in serving bowls, top with chapons and crab mixture, and serve scattered with chervil sprigs, extra chives and lemon wedges.
