Pop the chicken in the oven to cook, if you don't already have cooked chicken
Meanwhile, make the guac , and toss it in the fridge. Also, while the chicken cooks, you can make the cilantro rice.
Get your toppings assembled: grate cheese, shred lettuce, spoon out a bowl of salsa, etc.
Chop the chicken into bite sized pieces.
I layer my plates/bowls in this order: rice, beans, chicken, salsa, guacamole, lettuce, cheese
