When I first moved into my neighborhood, my neighbor brought over something folded into a tortilla for both my husband and I. She said it was a typical breakfast and she wanted to share something from her culture. It turns out she handed us each a Baleadas, a tortilla with refried beans, a little sour cream, and a little queso fresco. We thought it was very good and we were quite touched. She said sometimes you could put eggs and other ingredients in there too.
Traditionally this recipe is cooked with mustard oil for its pungent flavor, however, mustard oil is not sold in the United States for cooking purposes because of its high level of erucic acid.
