Preheat the oven to 400 degrees F. Line a straight-sided baking sheet with parchment paper.
In a pie plate or shallow bowl, mix together the panko and matcha powder. In a separate bowl, mix the flour and 1/2 teaspoon of the salt. Beat the eggs in a third shallow bowl.
One tender at a time, dredge the chicken in the seasoned flour, then in the egg, and then in the matcha panko. Place the breaded tenders on the prepared baking sheet. Brush an almond slice with a little beaten egg and place it on the tip of a tender "finger." Repeat with almond slices for the remaining tenders.
Bake the tenders until lightly golden and cooked through, 12 to 15 minutes. Sprinkle with the remaining 1/2 teaspoon salt. Place 1 tender in each hot dog bun and squirt ketchup "blood" over the fingers.
