In a mixing bowl, combine olive oil, cumin, paprika, garlic powder, salt, and black pepper. Add chicken strips and marinate for at least 15 minutes.

Preheat the grill to medium-high heat. Grill the marinated chicken for about 5-7 minutes on each side until fully cooked.

Grill the corn until charred, about 10 minutes. Allow to cool, then remove kernels from the cob.

In a bowl, mix the corn kernels with mayonnaise, cotija cheese, lime juice, and cilantro.

In a serving bowl, layer cooked rice, grilled chicken, street corn mixture, black beans, avocado slices, and cherry tomatoes.

Serve with lime wedges on the side.
