In a 10-inch pan over medium high heat, add oil. To the hot oil, add minced ginger and garlic and let them sizzle for 2-3 seconds. Add the ground pork. Mix well and brown the meat, breaking up all the clumps. You want some crispy parts, but mainly you want to cook the pork well.
While the meat cooks, chop up the green onions and cilantro. Mix them in a bowl and set aside.
After about 8 minutes when the meat is almost done, push the meat to the sides to create a small space in the middle. Add the sliced green and red chilis.
Pour in soy sauce, sesame oil, the sambal olek if using and stir well.
Turn off the stove and let the pork rest uncovered for 3-4 minutes to cool a little.
Stir in the chopped green onions and cilantro. Sprinkle the lemon juice and stir well.
Separate the butter lettuce leaves and allow your diners to serve themselves some of the spicy pork mixture into each butter lettuce, leaf. Or skip the lettuce and just eat the meat—good either way.
You can substitute any kind of ground meat for this recipe.
If you use leaner meat like ground chicken or turkey, you may need to add a little bit of oil.
If you plan to meal prep this, make the sauce and ground meat with seasonings ahead of time, but don't mix in the cilantro and onions until the last minute.
For the carb eaters, serve with rice. For low carb, serve in lettuce cups or even over a mixed green salad.
