I found it very hard in the beginning to find really good gluten free pastas. Here are the ones that I recommend. I like pastas made with corn or quinoa.
Rienzi (yellow box) brand for penne is good
I found a wonderful lasagne pasta that I highly recommend… the brand is PastaMia…visit www.biaglut.com. I purchased it from a store in Monroe, N.Y. called The best of Little Italy.
