In a large container, whisk together the soy sauce, olive oil, Worcestershire sauce, garlic, and lemon juice to create the marinade.
Add the chicken breasts, ensuring they are fully coated. Cover and refrigerate for at least 15 minutes but no longer than an hour.
Heat your grill to medium (around 400-450°F). Ensure the grates are clean and lightly oiled.
Remove the chicken from the marinade, allowing excess to drip off. Grill on direct heat for 4-6 minutes on each side until nicely seared.
Move the chicken to indirect heat and cook for an additional 5-7 minutes, or until the internal temperature reaches 160°F. Let rest for 5 minutes before slicing.
For the corn, lightly drizzle with olive oil and sprinkle with salt. Grill on high heat, turning every 2-3 minutes, for 8-10 minutes until charred. Let cool before cutting kernels from the cob.
In a large bowl, mix the grilled corn with mayo, feta, cilantro, lime juice, garlic, chili powder, paprika, salt, pepper, red onion, and cotija cheese. Adjust seasoning as needed.
Assemble your bowls by dividing rice, chicken, and street corn salad among the dishes. Add black beans, cherry tomatoes, jalapeño slices, and any toppings you'd like, such as avocado or sour cream.
