In a bowl, combine diced chicken with olive oil, chili powder, garlic powder, salt, and pepper. Let it marinate for about 20 minutes to absorb flavors.
In a large skillet over medium-high heat, add the marinated chicken. Cook for 6-8 minutes until browned and cooked through, stirring occasionally. Remove the chicken and set aside.
In the same skillet, add a little more olive oil if needed, and toss in the corn kernels. Sauté for 3-5 minutes until they start to caramelize slightly.
In a serving bowl or plate, layer cooked jasmine rice as the base. Top with the sautéed corn, cooked chicken, halved cherry tomatoes, diced avocado, and chopped red onion.
Squeeze fresh lime juice over the bowl and sprinkle with cilantro and feta cheese (if using). Add hot sauce if you like a spicy kick.
Mix the bowl slightly before eating to combine the flavors, or serve it as is for a pretty presentation. Enjoy your flavorful street corn chicken rice bowl!
