When I was growing up in SoCal in the 70’s and 80’s, we used to go to Mexican restaurants for dinner, and the dinner plates usually came with refried beans and Spanish rice. Then it seemed that in the 90’s, black beans came into vogue, and that appeared as a choice on menus. In Texas, we also have charro beans, which I had never had or even heard of before moving here. Although I like both black beans and charro beans, I still prefer good ole refried beans, given the choice.
