Yesterday, I made a freezer full of lumpias with about 3# of hamburger (and an additional 4# of pork, lumpia shanghai).
Cut up carrots, I used leeks instead of onions, garlic, turnips, soy sauce, spices, and formed all this into a mixture.
Lay out on a lumpia wrapper (I’d bought 4 – 5 containers of these at Jungle Jim’s the day before, he has at least 7 – 8 different brands of these) about the dia. of your finger, wrap up and freeze the excess for later, and fry a bunch in the wok.
I prefer the pork lumpias myself, but hamburger is good to.
