BBQ sauce marinade

My post for this challenge isn't very exciting. We barbecued some chicken on Labor Day last week, and I marinated with a little BBQ sauce. I thawed the chicken breasts, poked them with forks, and then put them in a giant Ziploc bag. I poured in some Pepsi and some BBQ sauce, in about equal portions. Squeezed most of the air out, zipped it up, squished it around, and stuck it in the fridge. I let it marinate for about 30 minutes, turning and squishing it once or twice during that time.
