The easiest appetizer you can make, these tuna bites are quickly seared and topped with a spicy mayo sauce. Put on radishes, jicama, or rice cakes for a delicious and healthy snack.
Over medium high heat, add a small amount of oil in a pan and sear your tuna. 1 minute per side for rare, 2-3 minutes per side for medium rare. Remove from pan and allow to cool, then slice into small cubes.
In a separate bowl, combine hot sauce with mayonnaise and slice your watermelon radish about 1/4" thick. Top radishes with tuna, drizzle with spicy mayo, and add chives on top. Serve immediately.
If you can't find watermelon radish, substitute thick slices of jicama, cucumber, wonton chips or rice cakes.
