What can I make with the broken corn chips at the bottom of the bag?

They're generally good for adding some crunch, too, not just the flavor. A few things that come to mind:

• on top of a salad - my family does a roasted corn and black bean salad; also probably good instead of croutons in salads where they're a better flavor/style fit

• garnish on a soup - tortilla soup, sopa de elote...

• as part of a breading for fish or chicken (or anything else to bake or fry)

In general, anywhere you would use breadcrumbs, tortilla chip crumbles might find a place. If you're afraid they're too salty, you could always put dump them in a sieve and shake some of the really small bits out, leaving the more sizable bits of chip.

Throw them in the frying pan with an egg. You'll get a crispy crunchy egg tortilla matrix.

I sometimes add the crumbs (or more, if there's not enough) to chili (chili con carne) as a thickener.

I think Angelina Jolie (of Tomb Raider fame) uses these crumbs for crumb crust. Not sure about that factoid, but hey. You can actually use these crumbs that way.

Put them on top of a tuna casserole with peas , celery , cream of mushroom soup, garlic , onions , bell peppers ( if you like them ) some cumin , coriander , a little curry , tuna , spinach fettuccine ...I don't think I'm leaving anything out ...yum , just made myself hungry , damn!
