This version of the classic dish substitutes scallions for cheese. Serve with Baby Bok Choy with Chile and Garlic.
Preheat oven to 350 degrees. In a medium skillet, heat oil over medium-high. Add onion, garlic, snow peas, and celery and cook, stirring occasionally, until onion is soft and vegetables begin to brown, 5 minutes. Add ginger and sesame oil, season with salt and pepper, and cook, stirring, 1 minute.
In a large bowl, combine pork, scallions, bread, and egg. Add vegetable mixture and season with 2 teaspoons salt and 1/2 teaspoon pepper. Using your hands, mix until ingredients are combined. Transfer to a parchment-lined rimmed baking sheet; form into a 4-by-10-inch loaf. Bake until meatloaf is cooked through, 40 minutes, rotating sheet halfway through. Let rest 15 minutes before slicing.
You can substitute ground turkey for the pork, if desired.
