Cook noodles according to package instructions to al dente. You want them slightly under-done. Reserve about 1/2 cup of the pasta water before draining.
Whisk all sauce ingredients together in a bowl, set aside.
Add all-purpose meatballs to a large microwavable bowl. Add about 1/2 cup water. Microwave for 4-5 minutes, stirring in-between each minute until warm.
Drain pasta, add pasta back to pot on a med-low stove, add sauce and toss pasta to coat. Thin sauce out if needed with reserved pasta water. Toss in warmed meatballs. Once all combined and warmed through, garnish with sesame seeds and chopped scallions, and optional chopped peanuts for crunch.
Make it vegetarian and leave out the meatballs. Add your favorite veggies like bell peppers, onions, and broccoli!
