Assembly
Step 1
In a large pot filled with heavily salted water, add fingerling potatoes and bring to a boil. Once boiled, reduce heat to simmer and cook until potatoes are tender. Transfer to an ice bath without dumping the water.
Step 2
In the same pot, return water to a boil and blanch the green beans. Transfer to ice bath.
Step 3
Again, in the same pot, return water to a boil and carefully lower the eggs in. Simmer for about 6.5-7 minutes. Remove and transfer to ice bath.
Step 4
To assemble: Slice ciabatta buns in half and toast. Slather with Hot Deli Mustard and mayonnaise. Drain the canned tuna and spread onto the bottom half of the bun. Spread olives out on top of the tuna.
Slice fingerling potatoes lengthwise and evenly spread out the slices onto the bun. Add a layer of green beans, sliced tomatoes, and pickled onion. Drizzle with Honey Yuzu Dressing. Cut the jammy egg in halves or quarters, and place on top. Place the top half of the bun onto the sandwich and enjoy!
