Can I make this tuna salad ahead of time?
Yes, but add the avocado just before serving to prevent browning. Store other ingredients in an airtight container in the refrigerator for up to 2 days.
How much heat does the jalapeño add?
One jalapeño adds mild-to-medium heat depending on your tolerance. Remove the seeds and ribs for less spice, or omit entirely if you prefer no heat.
What can I use instead of mayonnaise?
Greek yogurt, sour cream, or crema work well as creamier alternatives. Use the same 1/2 cup amount, though Greek yogurt may make the salad slightly thinner.
Is this recipe gluten-free?
Yes—the salad itself is naturally gluten-free. Serve it with gluten-free crackers or bread if needed.
How do I drain canned tuna properly?
Place the opened can in a fine-mesh strainer and press gently with a fork or the back of a spoon to remove excess liquid without breaking apart the tuna.
