In a medium bowl, whisk together the barbecue sauce, honey, soy sauce, minced garlic, and smoked paprika until homogenized.
Heat the vegetable oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken cubes to the skillet in a single layer and sear for 6 to 8 minutes, turning occasionally until an internal temperature of 165°F (74°C) is reached.
Reduce the heat to medium and pour the honey BBQ sauce mixture over the chicken.
Simmer the sauce for 3 to 5 minutes, stirring constantly, until the glaze has thickened and coats the chicken thoroughly.
Divide the cooked rice into four serving bowls.
Top each portion of rice with the glazed chicken and excess sauce.
Garnish with sliced green onions and toasted sesame seeds.
