Arrange chicken, bell peppers and onion in a single layer on the prepared baking sheet. Drizzle with olive oil; toss to coat. Sprinkle with the seasoning blend; toss to coat again.

Bake for 20 minutes, or until the chicken is cooked through and the vegetables are crisp-tender, stirring halfway through. Drizzle with lime juice and serve immediately.
