For 30 lumpia:
1 lb ground pork
1 lb bratwurst
2 carrots, minced
2 celery stalks, minced OR a big handful of finely shredded cabbage
1 small mild onion
2 or 3 cloves minced garlic
a few shakes of soy sauce
a shake or two of crushed red pepper
30 lumpia wrappers (you can get them at any Asian grocery, usually in the freezer section. Don't substitute eggroll or springroll wrappers because it's not the same thing.)
peanut oil
Squeeze the brats out of the casing and fry up with the pork and a few shakes of soy sauce, chopping into fine bits.
Remove the meat from the pan, pour out the fat, and saute the celery, carrots and onion for about 5 mins.
Add the meat back to the pan, mix well, and let it cool.
Lay out your lumpia wrapper and place 1 heaping tablespoonful of meat mixture along the bottom third of the wrapper. I always over fill them
Then you roll them up eggroll or burrito style, but you want them to be nice and tight. There are videos on the 'net where some nice lady will show you how.
Fry in hot peanut oil until golden, about 2.5 mins, turn, then another 2.5 mins.
