What you’ll need

Helpful details

A few things worth knowing

  • Fold the tuna and beans gently with a spoon or spatula to avoid crushing the bean skins.
  • Press the tuna lid lightly against the can while draining to remove as much moisture as possible.
  • Add a pinch of salt and cracked black pepper alongside the oregano to lift the bean flavors.
  • Ensure your bento container has snug dividers to keep the olive brine from seeping into the tomatoes.
Variations

Ways to make it your own

  • Arugula base: Line the main compartment with a small handful of peppery baby arugula before adding the tuna and beans.
  • Citrus accent: Tuck a fresh lemon wedge into a spare compartment to squeeze over the fish right before eating.
