Trim fat off chicken thighs. Add to a bowl with 4 teaspoons olive oil and balsamic vinegar. Toss with tongs to coat. Sprinkle chili powder, paprika, cumin, garlic powder, dried oregano, onion powder, salt, and pepper on top. Toss again until chicken is evenly and well coated.
Place the chicken smooth side down in a single even layer in the basket of an air fryer. Air fry for 10–12 minutes at 400℉ or until chicken registers 160℉. Remove to a cutting board and let rest 5 minutes before thinly slicing. Squeeze lime over chicken if desired.
Set a large non-stick, 12-inch pan over medium-high heat. Add 2 tablespoons oil. Once oil is hot, add sliced bell peppers and onions in an even layer. Season with salt and pepper. Stir only occasionally until tender and charred all over, about 10–12 minutes. Remove to a plate.
Divide prepared rice evenly among four bowls. Add chicken strips and bell pepper mixture to the bowls. Add toppings. Enjoy immediately.

Notes
Note 1: If you'd rather use chicken breast, thinly slice into small strips. Toss with oil, vinegar, and seasonings. Sauté until cooked through and tender. Then use the same pan to cook the veggies. Stir only occasionally so the chicken gets nicely charred.Note 2: I love to top these bowls with guacamole, sour cream, black beans, fresh lime wedges, cilantro, green onions, and fire-roasted corn. If you're a sauce person, you've got to try this homemade Cilantro Lime Sauce or this store-bought sauce.Nutrition: The nutrition facts do not include any toppings.Storage: Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat chicken and veggies before serving. Keep toppings separate for freshness.
