Cook rice noodles following package directions.
In a wok, saute firm tofu, red peppers, onion, and grated ginger in veggie oil until the tofu is browned a bit and the veggies are crisp tender. Add some mince garlic and saute another minute. Toss in the noodles, a pinch of red pepper flakes, soy sauce to taste, and the juice of a lime. Saute another minute. Add chopped cilantro and peanuts and toss before serving.
