Follow the package instructions to boil the glass noodles. Drain the noodles and cool them under cold, running water, then finely chop. Pre-packaged pho spice blends can be found in Asian markets. Use the dried and ground spice blends and not canned pho spice paste. If you don't have a deep fryer, the dumplings can be boiled in heavily salted water until they float, drained on a paper towel, and then pan-fried in a large skillet and in 1 tablespoon of canola oil until golden-brown.
