<human>:  How can I cook a vegan stir-fry?
<bot>: To make a vegan stir-fry, you will need a selection of your favorite vegetables, such as broccoli, mushrooms, carrots, and onions. Also, choose a plant-based protein source like seitan, tofu, or tempeh. To prepare the vegetables, cut them into bite-sized pieces. Heat a wok or large pan over medium-high heat and add your oil of choice (like sesame, coconut, or peanut oil). Add the vegetables, stirring and tossing occasionally, until they have softened and started to brown. Add your protein source, stirring continuously until it is cooked through. Serve over cooked rice or your favorite grain and add soy sauce or tamari to taste. Enjoy!
