Here's the other dish Mom made when she was in town: those noodles on the right side of this arrangement, chop chae. Again, I lack exact amounts, so some experimentation may be required.
Cellophane noodles, boiled and left to sit until they turn soft, then cut up
Spinach, boiled and drained
Meat or scrambled egg (optional)
Mix and fry in oil. Add soy sauce afterwards to taste.
