Preparation Heat oil in a large skillet over medium-high until hot. Cook tofu in a single layer, undisturbed, until golden brown on one side, about 8 minutes. Turn and continue to cook until golden on the other side, about 6 minutes. Transfer to a paper towel-lined plate. Cook peppers in same skillet, stirring frequently, until beginning to soften, about 5 minutes. Meanwhile, cook noodles according to package directions. Whisk peanut butter, soy sauce, vinegar, brown sugar, fish sauce, and lime juice in a medium bowl to combine. Toss tofu, noodles, peppers, peanut butter sauce, and spinach in a large bowl. Transfer to a platter. Top with cilantro and peanuts. Serve with lime wedges alongside.
