Rinse 1 cup of jasmine rice under cold water until the water runs clear. In a medium saucepan, combine rinsed rice with 2 cups of water. Bring to a gentle boil, reduce heat to low, cover, and simmer for about 15 minutes until water is absorbed and rice is tender. Remove from heat and keep covered for 5 minutes to steam.
Whisk together 1/4 cup honey, 2 tablespoons sriracha sauce, and 1 tablespoon soy sauce in a small bowl. Adjust sriracha to preferred spice level.
Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Add diced chicken breast, season with 1 teaspoon garlic powder, salt, and pepper. Cook, stirring occasionally, until browned and cooked through, about 6 to 8 minutes.
Pour the hot honey sauce over the cooked chicken in the skillet. Toss to coat evenly and simmer for 2 to 3 minutes until the sauce thickens and clings to the chicken.
Thinly slice the medium cucumber and set aside.
Spoon jasmine rice into bowls, top with hot honey chicken, sliced cucumber, and garnish with thinly sliced green onions.
