Combine minced garlic, minced ginger, honey, soy sauce or tamari, and rice vinegar in a small bowl; stir until honey dissolves.
In another small bowl, mix together Greek yogurt, water, and Sriracha to create the spicy yogurt sauce.
Season the salmon chunks evenly with kosher salt and black pepper.
Heat olive oil in a large nonstick skillet over medium-high heat until shimmering.
Add salmon pieces in a single layer and cook without moving until the bottoms are golden brown, about 2 to 3 minutes.
Flip the salmon and cook the other side until golden brown, about 2 to 3 minutes more.
Pour the honey-soy sauce mixture over the salmon and cook, stirring and spooning sauce over the fish occasionally, until the sauce thickens and glazes the salmon, about 2 to 3 minutes. Turn off heat.
Divide the cooked rice between bowls, top with glazed salmon, spoon pan sauce over, and add desired toppings.
Drizzle the prepared Sriracha yogurt sauce over the bowls before serving.
