Tuna Salad Tips
- Trimming your beans. This can be tedious, but it doesn’t need to be. Grab a handful and line them up on one side. Trim the ends using a sharp chef’s knife. Then, do the same on the other side!
- No more intense red onions. Rinse your red onion slices under cold water before serving to help reduce that strong onion bite.
- Storing tuna salad. This salad actually gets better after sitting in the fridge overnight, making it a great option for meal prep lunches. Make a big batch at the beginning of the week and have it for lunch every day. Covered in an airtight container, this salad will last up to seven days in the fridge.

Ingredients
Method
- Bring a medium pot of water to boil and season generously with salt. Meanwhile, trim the ends of 350g green beans, thinly slice 1 red onion and make a batch of Italian dressing.
- When the water boils, drop the green beans and cut the heat. Let cook for 2-3 minutes, or until bright green. Meanwhile, prepare an ice bath. When the beans are green, transfer to the ice water, along with sliced red onion. After 1 minute, remove and transfer to a salad spinner or clean dish towel to dry.
- To a small bowl, add red onion slices, 1 tsp sumac and the juice of 1/2 lemon, toss and set aside while you make the salad.
- To a shallow serving bowl, add cooked green beans, 1 cup pitted Kalamata olives and 1/4 cup capers. Drain the oil from 3 cans of tuna, then add to the bowl and cover everything in Italian dressing. Toss to evenly coat, then finish with sumac red onions and a drizzle of olive oil.
