Notes
Seasonings, especially salt, are guidelines. Adjust to taste.
The hot sauce doesn't make the salad overly spicy. Add an extra tablespoon if you want it truly spicy.
When choosing a hot sauce, it's best to use one with the first ingredient listed as hot peppers rather than vinegar. Those tend to be the most flavorful. I like the flavor of sriracha, so that's what I use.
Since I use water-packed tuna, I add quite a bit of mayo - 6 tablespoons. Otherwise, the salad is too dry.
You can use oil-packed tuna, but make sure it's packed in pure olive oil, not soybean or cottonseed oil. You can use less mayo with oil-packed tuna - four tablespoons should be enough.
You can keep the leftovers in an airtight container in the fridge for up to 4 days. Remix the salad before serving it. I don't recommend freezing the leftovers.
