# Expert Tips:

01 -
  • Ten minutes from fridge to plate, which means lunch actually happens instead of getting derailed.
  • It tastes indulgent and fresh at the same time, so you never feel like you're sacrificing flavor for health.
  • The cucumber stays perfectly crisp if you don't make it hours ahead, giving you that textural satisfaction that makes eating feel intentional.
02 -
  • Avocado oxidizes quickly, so if you're making this more than an hour ahead, toss the avocado pieces with a little extra lemon juice to keep them from turning brown and sad-looking.
  • The cucumber boats will start to weep their water after a while, so these are best eaten within an hour of assembly—they're a fresh, right-now kind of meal.
03 -
  • Chill your serving plates or bowls before plating so the avocado and tuna stay cool longer and everything tastes fresher.
  • If you're making these for guests, assemble them right in front of people—there's something satisfying about watching the boats get filled, and it tastes better when you know exactly what went into it.
