Cook the rice or noodles, as desired.
Heat 1 tablespoon oil in a 12-inch nonstick skillet or wok over medium-high heat.
Cook your choice of protein until almost opaque; transfer to a plate.
Add the remaining tablespoon oil, followed by the garlic, ginger, pinch of salt and sugar; stir-fry 30 seconds.
Add the onion and cook until softened, about 2 minutes. Stir in the veggies and cook until crisp-tender, approximately 4-5 minutes more.
Return the protein to the pan, immediately pour the sauce over everything, and cook, stirring to evenly coat, until sauce is thickened, 2 to 3 minutes.
