Storage Tips
You can keep leftover tuna salad sealed in the fridge for up to two days For best texture store the veggies and dressing separately and mix just before serving if you plan to prep ahead Avoid freezing as the texture of the yogurt and fresh vegetables can change
Ingredient Substitutions
Instead of Greek yogurt you can use plain skyr or a dairy free yogurt for a similar creamy effect If you do not have fresh parsley try dill or chives for a different herbal note Swap in yellow or green bell pepper if that is what you have or use scallions for a milder onion flavor
