I've had several frozen brands of gluten free ravioli but none of them even come close to fresh pasta. I recently discovered a brand called Manini's. I don't know anything about the company but one thing I can tell you is their gluten free raviolis are fantastic. So far I have bought them 3 or 4 times and have tried two flavors and I love them. I have only purchased them at my local Whole Foods in Northern California. If you ever come across these I suggest you purchase them but fair warning they are delicious!
You can find Manini's on their website
