When it comes to junk foods, chips are my weakness. I fucking love chips. I've always been a huge fan of the hot cheetos and were always one of my favorite chip back home, until i've been introduced to some of the chips of Mexican brands.
Takis:

They are essentially just corn chips that look like a tightly rolled mini-tortillas. They are crunchier than your average corn chip. Chile and Lime is one of my favorite flavor combos ever, and I season tons of food with the seasoning. These have a stronger lime flavor as opposed to being overly hot. Goddamn, I love these chips. They are like crack to me. They have a hotter flavor "Nitro" but they aren't near as good flavor wise. I'm not sure if you guys have the ability to get these other than maybe the Texas/Cali folks. I highly recommending them if you get the chance.
Turbos Flamas:

Sabritas is the Mexican name for Frito Lay, so the availability is probably a little higher than the aforementioned Takis. Again another chile and lime flavored chip. They kinda have a rotini look to them and are hotter than the Takis. These two are head to head as my favorite two chips. They are awesome.
And to go off in a different direction:
I could probably crush a box in a sitting. I've never attempted to do so, but fuck, Oreos are so damn good. Serving size, 3 cookies? I eat those bitches by the row!
Honorable Mention:
I love me some pizza rolls as well, but I'm wanting to leave this thread toward the not-having-to-cook-it snacks.
What do you guys eat for garbage snack food probably more often than you should?
