It's a brand of cereal, with quite a few different varieties.
Check out their web site
here - they sell other products, too, like bars and crackers (the cheese ones taste just like Cheese Nips
).
Since you're a fellow Pittsburgher, check your local Giant Eagle. The one I shop at (Village Square Mall) has a separate health food section and that's where all the Kashi products are.
My favorite Kashi cereal is GoLean because it's crunchy, low in sugar, and high in protein and fiber. I mix it in with low fat cottage cheese and a little dry SF chocolate pudding mix.
