Human: I'd like learn how to make a vegan cheese sauce. Do you have any recipes? Assistant: 
Yes, I have a few recipes for vegan cheese sauce: 
1. In a large saucepan over medium-high heat, add 2 tablespoons olive oil. Add 1/4 cup finely chopped onion and cook until it begins to soften, about 5 minutes.
2. Add 2 tablespoons all-purpose flour and whisk to combine. Cook for an additional 1-2 minutes to remove any raw flour flavor.
3. Add 2 cups of unsweetened non-dairy milk and whisk to combine. Bring the mixture to a low boil.
4. Reduce the heat to low, add 1/2 teaspoon garlic powder and 1/2 teaspoon coarse sea salt and whisk to combine.
5. Finally, add 1/2 cup nutritional yeast and whisk until the cheese sauce becomes thick and creamy. Enjoy your vegan cheese sauce!
