Preheat the broiler. Adjust the rack to the middle position.
Mix together the miso paste, lime juice, sesame oil, soy sauce, honey, ginger paste and garlic. Toss the salmon in the mixture until fully coated and arrange in an even layer on a baking sheet.
When the broiler is preheated, broil the salmon bites until just cooked and browned on top, no need to flip, takes about 5-7 minutes.
Toss the carrots and cucumbers in rice vinegar and sea salt.
In a bowl, add rice, cooked salmon, peeled carrots, and thinly sliced cucumbers. Top with sesame seeds and cilantro leaves.
