Frequently Asked Questions
Can I double this recipe?
Yes, simply double all ingredients. It is perfect for meal prep, though you may want to add the fresh cucumber just before serving for maximum crunch.
Is it okay to use tuna in water?
You can use tuna in water, but we recommend adding an extra tablespoon of high-quality olive oil to ensure the salad remains rich and flavorful.
Can I make this ahead of time?
Absolutely. The flavors actually improve after sitting in the fridge for a few hours. Just give it a quick toss before serving.
What if I don’t have cannellini beans?
Great Northern beans or even navy beans make excellent substitutes with a similar creamy texture.
How do I keep the onions from being too sharp?
If you find raw onion too intense, soak the diced pieces in cold water for 5 minutes, then drain and pat dry before adding to the salad.
