Slice salmon into ¼ inch sashimi slices.
Place 1 tablespoon stracciatella in a small heatproof bowl.
Lay one piece of salmon on top of the stracciatella and season with a pinch of flaky sea salt.
Using a kitchen torch, gently sear the salmon until it just starts to color.
Top the salmon with a slice of tomato, then a piece of pickled daikon radish.
Garnish with everything bagel seasoning and serve immediately.
