In a small saucepan over medium heat, whisk together peanut butter and water. Add garlic, lime juice, molasses and soy sauce. Simmer until sauce thickens, about 5 minutes. Meanwhile, put rice noodles in a large bowl and cover with hot water. Let soak for 20-25 minutes, until tender. Dice tofu into 1/2" cubes, and saute in oil over medium-high heat until browned, sprinkling on ground ginger as it cooks. If using veggies, saute them in a little more oil until cooked through. When everything is ready, assemble noodles, tofu and veggies in a serving bowl. Top with sauce, and stir until combined. Serve hot with red peppers sprinkled on top.
