Ingredients for Tuna Lime Tostadas

Technique Tip for This Recipe
To enhance the flavor of the tuna mixture, consider adding a pinch of salt and pepper when combining the lime juice and cilantro.

How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the tostadas on a baking sheet and cover them loosely with aluminum foil to prevent them from drying out. Heat for about 10 minutes or until the tuna mixture is warmed through.
If you prefer using a microwave, place the tostadas on a microwave-safe plate. Cover them with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 1-2 minutes, checking halfway through to ensure they are evenly heated.
For a quick stovetop method, heat a non-stick skillet over medium heat. Place the tostadas in the skillet, cover with a lid, and heat for about 2-3 minutes. This method helps maintain the crispiness of the tostadas while warming the tuna mixture.
If you have an air fryer, preheat it to 350°F (175°C). Place the tostadas in the basket in a single layer. Heat for 3-4 minutes, checking halfway through to ensure they are not overcooked.
To reheat using a toaster oven, preheat it to 350°F (175°C). Place the tostadas on the rack or a baking sheet. Heat for 5-7 minutes, keeping an eye on them to prevent burning.
If you want to refresh the toppings, you can reheat the tuna mixture separately in the microwave or on the stovetop. Then, assemble the tostadas with fresh lettuce, tomatoes, and a new dollop of sour cream before serving.
