Pesto Tuna Pasta Bento Box

Cold pasta salads make some of the most reliable packed lunches, especially when spiral shapes like fusilli catch every bit of dressing. In this simple bento assembly, cooked pasta is coated in rich basil pesto before being gently tossed with olive-oil-packed tuna and juicy cherry tomato halves. A final scatter of pine nuts adds a buttery crunch over the top. Because the components hold up well when kept chilled, it is a practical option to prepare in advance for work or school days.
Why this one works
- Fusilli spirals hold the basil pesto thoroughly in every groove.
- Tuna packed in olive oil brings rich flavor without requiring heavy sauces.
- Halved cherry tomatoes provide juicy bursts of acidity that balance the pesto.
- Pine nuts add a subtle nutty crunch right before serving.
- Assembles rapidly once the pasta has cooked and cooled down.

What you’ll need
- 8 oz (225g) fusilli pasta Cook just to al dente so the spirals maintain their structure when tossed cold.
- 1 cup (150g) canned tuna in olive oil, drained Drain the excess oil well so the pasta salad remains light and clean-tasting.
- 1/2 cup (120ml) fresh basil pesto Tosses smoothly across cooled pasta, providing herbaceous richness and garlic depth.
- 1/4 cup (30g) cherry tomatoes, halved Slice cleanly across the center to keep juices from releasing excessively into the pasta.
- 1/4 cup (25g) pine nuts Sprinkled on top at the end to preserve their delicate crisp texture.

Quick recipe answers
Can this pasta salad be eaten warm?+
This recipe is intended to be served cold, as the fresh pesto and flaky tuna maintain their best texture and flavor when chilled.
Why should I cool the pasta before adding the pesto?+
