Soy sauce, sesame oil, rice vinegar, Serrano pepper, lime juice, mint, and sesame seeds should all be combined in a medium bowl.

Diced tuna should be added to a bowl and coated with the soy sauce mixture.

On top of six individual crackers, chips, or stacks of microgreens, assemble equal portions of tuna ceviche. Alternately, you might use roasted sweet potato slices as the basis, like Dos Caminos does.

Add a slice of Serrano pepper and some black sesame seeds as a garnish.
