<human>:  Can you please find me a recipe for a vegan alternative to lobster bisque?
<bot>: For a delicious vegan alternative to traditional lobster bisque, you can try making a vegan mushroom bisque. Start by heating a tablespoon of olive oil in a pot over medium heat. To this, add one finely chopped onion, two cloves of minced garlic, and one finely chopped celery stalk. Cook until the vegetables are soft. Then, add 8 ounces of sliced mushrooms, 2 teaspoons of dried thyme, one teaspoon of paprika, and ½ teaspoon of freshly ground pepper. Cook the mixture for another 5 minutes. Then, pour in 4 cups of vegetable broth and stir the ingredients together. Bring the mixture to a boil and reduce the heat. Simmer for about 20 minutes. Finally, stir in 2 tablespoons of cornstarch that has been dissolved in a few teaspoons of cold water. Cook until the broth thickens. Serve your vegan mushroom bisque warm. Enjoy!
