A few weeks I was working long hours and coming home late in the evening, so dinner was leftovers. We had chicken tacos over the weekend and made a huge amount of pick de gallo and guacamole. We also had a lot of extra corn tortillas. By the end of the week I ran out of chicken, but had a container of cooked quinoa in the refrigerator, hence quinoa tacos. Finding ingredients to put in a corn tortilla shell is a great way to clean out the refrigerator too.
