Herbs – Add a few tablespoons of fresh herbs like – parsley, chives, rosemary, dill, or cilantro. You can also leave out the herbs altogether if you don’t have any on hand.

Chicken – I am using chicken tenderloin, you can buy them on sale at a very good price. If not, thinly pounded (cut in half horizontally) boneless, skinless chicken thighs or breasts will also work.
