Cook the rice and set aside in two serving bowls.
Prepare the corn: grill it (or heat in a skillet) until lightly charred. Toss with mayonnaise, cotija cheese, smoked paprika, chili powder, and a squeeze of lime juice.
Grill the chicken: season with salt, pepper, and a little chili powder, then grill until cooked through. Slice into strips.
Assemble the bowls: layer rice, grilled chicken, and street-corn mixture.
Top it off with avocado slices, diced onion, fresh cilantro, and an extra sprinkle of cotija. Add lime wedges on the side for serving.
