Very good! I didn't have shrimp or ground beef this evening, so I used ground pork which I seasoned very well with salt, pepper, and onion powder before adding to the veggie mixture. I also did not have celery but still wanted the crunch factor - so I chopped up some water chestnuts and added those instead. Also, I used beef bollioun (dry) instead of MSG because I never use it in our home. Also, I didn't have oyster juice, so I used 3 TBS of chicken stock instead (which was fine since this roll didn't have shrimp in it). I would suggest salting the veggies well prior to sweating them as this helps to wilt them. Drain the water off of the veggies and drain the browned pork before combining. Be careful with the heat of the oil. These cook fairly quickly so keep a close eye on them. I used canola oil to fry ours because it is a healthier option (no olive oil as it will burn at that temperature).
