In a large bowl, add pork through lemon zest. Use your hands to gently mix until well-combined. Shape into 16 1-inch meatballs.
Add oil to a heavy skillet. Heat pan over medium heat. Once oil is hot, add the meatballs in a single layer, working in batches if necessary, and cook for 4 minutes. Flip and continue cooking for 10 to 15 minutes more, rotating often, or until golden brown on all sides and cooked through (internal cooking temperature should reach 160°F).
Transfer meatballs to a paper towel-lined plate to drain briefly, then into a clean mixing bowl. Toss with hoisin sauce to taste while meatballs are still hot.
If desired, divide meatballs into meal prep containers with cooked brown rice noodles, sliced vegetables, and extra hoisin.
