For the past few months, Costco has only had beef patties available, so as Cas shopped with the Mexicans, I headed over to grab some items for us. Like I have done each week, I checked to see what type of patties they had; we liked the sirloin patties the best. As I got closer, I noticed two options. Could it be? Our favorite is back? The answer was no, but our second favorite was, so I bought two.
