Unfortunately, I don't have a taco truck parked on my front yard. And I'm lazy. This really limits my options at 1am when I'm hungry. Driving is out of the question, but walking to the refrigerator is doable. Most every night, I consume a generous serving of chips and salsa (queso if I'm feeling crazy). Here's what I typically eat:
El Milagro. These are the best chips I've found at the grocery store. They're not the ultra-thin kind, but they aren't the super-thick ones either. They are a nice median. If there are better ones around, I'd love to know.
Sabor! I just discovered this salsa at Central Market (I think you can grab it at some HEBs, too). I love the red. It is fresh-tasting and hot, probably due to the generous amount of serrano peppers in it. I really can't wait until I finish this jar so I can try out their green salsa as well.
Honorable mentions: Ana's and Rose's salsas.
