Warm a large skillet or dutch oven over medium-high heat. Toss in the chicken along with 1 teaspoon salt, pepper, garlic powder, and paprika, then cook, stirring frequently until the chicken is nearly done, about 5 minutes.
Add the sliced onion and red bell peppers plus a pinch of salt. Continue cooking for 5 minutes, stirring now and then until vegetables soften.
Mix in the minced garlic and sauté for an additional minute until fragrant. Stir in the tomato paste and rinsed jasmine rice, coating everything evenly.
Pour in the chicken broth along with the remaining teaspoon of salt, and stir to combine. Bring the mixture to a gentle boil.
Once boiling, cover the pan, reduce the heat to low, and let it simmer for 15 minutes until the rice is tender and liquid absorbed.
Turn off the heat but keep the pan covered, allowing the dish to rest for 10 minutes.
Remove the lid, fluff the rice with a fork, and serve immediately while hot.
