# Expert Advice:

01 -
  • It's ready in less time than your coffee brews, so weekday lunches finally feel manageable.
  • The creamy avocado against crisp cucumber is genuinely addictive and feels indulgent without any guilt.
  • You can meal prep these boats on Sunday and have grabable lunches waiting all week long.
02 -
  • If you prep these more than a couple hours ahead, the cucumber will start weeping liquid and everything gets watery—assembly-line timing is your friend here.
  • Don't skip draining the tuna thoroughly, or the whole thing turns into a soggy mess within minutes of assembly.
03 -
  • Choose cucumbers that are similar in size so they fill evenly and look intentional on the plate instead of accidental.
  • If your avocado is borderline ripe, dice it and dress it with lemon juice immediately to prevent browning before assembly.
