Customize It – Add black beans, corn, or salsa for variety.
Make It Spicy – Stir hot sauce directly into the tuna or add chipotle for smoky heat.
Serving Suggestions

Mini Tostadas – Use smaller shells for appetizers or parties.
With a Side – Serve with a side of rice, beans, or Mexican street corn.
