To prepare a buddha delight vegan stir fry recipe, first you'll need to prepare the ingredients. First, you will need the following ingredients: 12 tsp. kosher salt, 1 tablespoon sriracha, 2 tablespoons soy sauce, 1/2 cup vegetable oil, and 1 teaspoon chile flakes. Heat the oil over medium-high heat. Add the garlic and stir-fry for 1 to 2 minutes, or until fragrant. Stir in the bok choy and cook for an additional 2 to 3 minutes. Remove the pan from the heat and add the carrots and celery. Cook for 3 to 4 minutes more, until the vegetables are crisp-tender. Season with salt and pepper to taste.
