In a large bowl, combine lettuce with basil, cilantro, black beans, corn, cheese and jicama. Toss with ranch dressing {as much as you'd like} and divide between two serving bowls.
Place diced tomatoes around the edges of each bowl, top with avocado slices and diced grilled chicken. Drizzle bbq sauce over top the whole thing and serve.
*If you did not grill your chicken with BBQ sauce, dice your cooled chicken breast, toss in a little bbq sauce, place on salad and drizzle with more sauce.
