Why You'll Love These Easy Appetizer Bites

Besides the fact that these are ridiculously simple to make, they're also super easy to eat. The watermelon radish slice is sturdy enough that is holds the tuna and toppings. They make a perfect little pass around canapé or appetizer before a dinner party.

I also sometimes just make a bunch of them and have them for lunch! If you like the pepper kick of a radish and a creamy (lightly spicy) tuna salad, then you've got to try these.

Ingredients for Radish Tuna Bites

This recipe is super simple and you don't need much to make it! Here's what to get.

Watermelon Radish - You'll need one watermelon radish. You don't need to peel it but make sure to scrub the outside well and pull off any little roots.

Can of Tuna - You'll need one, 12 ounce can of tuna. I used albacore, but you can use any type you like/have on hand.

Mayonnaise - You'll need 2 tablespoons of mayonnaise for this recipe.

Sriracha - You'll need at least 1 teaspoon of sriracha (or other hot chili paste). If you love spicy food, add a tablespoon instead of a teaspoon!

Kosher Salt - You'll need 1 teaspoon of kosher salt. Kosher salt is less concentrated than regular salt, so half this amount if you are using regular table salt.

Optional Toppings - You can use a pinch of paprika, sesame seeds, and microgreens to top these radish bites. They add great color and flavor!

Tips for Making this Recipe

Specialty Ingredients - If you can't find black sesame seeds at your grocery store, they're available online from The Spice House.

Storing Tips - This recipe is best served the day you make it, as the radishes get a little less crispy in the refrigerator.
