Put the shrimp, pork, garlic, egg, sugar, sambal oelek, fish sauce, lime juice, and salt in a food processor. Pulse until smooth and well combined. 

Mix in panko and cilantro.

Using your hands or a cookie scoop, form the meat mixture into 2-inc balls. Set aside on a platter. 

Heat 2-3 Tablespoons of oil in a large frying pan over medium-high heat. 

Cook the meatballs in batches for 8-10 minutes, turning to brown all sides. Remove meatballs to a paper towel-lined platter when working in batches.

Finish cooking all the meatballs and then return to the pan. 

Toss the meatballs with the Thai sweet chili sauce until well coated. Garnish with more cilantro. 

Serve with sticky rice.
