In a large bowl, mix olive oil, lime juice, chopped chipotle chilis, adobo sauce, garlic powder, and salt until combined.
Add the chicken strips to the marinade, toss well to coat, then cover and refrigerate for at least 2 hours or overnight for best flavor.
Heat a skillet over medium-high heat and place the marinated chicken pieces in the pan.
Cook the chicken, stirring occasionally, until fully cooked and browned, about 5 minutes, then set aside.
Bring water and salt to a boil in a pot, add the rinsed rice, then reduce heat to low and cover.
Simmer the rice for 15 to 18 minutes until the water is absorbed and the rice is tender.
Fluff the rice with a fork and stir in lime zest, lime juice, chopped cilantro, and salt to taste.
To assemble each bowl, start with a base of cilantro lime rice and chopped romaine lettuce.
Top the rice and lettuce with cooked chicken, diced tomatoes, thawed corn, black beans, chopped red onion, and dollops of guacamole or avocado.
Serve immediately or pack into meal prep containers for easy, healthy lunches throughout the week.
