While I've had some more authentic rice noodles from the market before, my favorite go-to brown rice noodles are Annie Chun's, which are found in the natural food section in your grocery store. For me, I typically find these are Kroger and absolutely love cooking with them. Here is a picture of the box:
These noodles take just a few minutes to cook (or you can even let them soak in water and they "cook" that way), and you're ready to go with a side. Here are some protein options if you want to try them out and have the veggies and noodles as side dishes:
Skillet Glazed Chicken from Food.com
General Tso's Chicken (from a pre-packaged mix - see previous post on this here)
Or, you can mix the noodles as more of the main portion of the dish, like this Pad Thai from Eatingwell.com. (My disclaimer for this dish would be to go very light on the fish sauce. It's an extremely strong flavor, and I think it needs to be cut to around 1/4 of what it calls for. With that said, you may need some additional flavor, so I add a bit of sesame oil and soy sauce or liquid aminos to make up for it.)
Hope you enjoy cooking with rice noodles as much as we do!
