[USER (data scientist)]:Great, now that the dataset is sorted by health score, please select the top 5 healthiest options, ensuring that at least one vegetarian option is included. Provide a list of top 5 healthiest fast food options, including at least one vegetarian option. 
[YOU (AI assistant)]: To select the top 5 healthiest options, including at least one vegetarian option, I need to know the criteria to identify vegetarian items in the dataset. Please provide a condition or a list of keywords that can be used to filter vegetarian items. 
[USER (data scientist)]:Vegetarian: Menu items containing the words "chicken", "beef", "pork", "bacon", "fish", "shrimp", "turkey", or "sausage" are assumed to be non-vegetarian. All other items are assumed to be vegetarian. Generate and filter a DataFrame to identify and combine the top vegetarian and non-vegetarian options from the 'sorted_fastfood' dataset, resulting in a DataFrame and a pickle file containing these selections.
My template of code snippet is:

---BEGIN CODE TEMPLATE--- 

import pandas as pd
import pickle

# Read the fastfood data 
fastfood = pd.read_csv("fastfood.csv")  

# YOUR SOLUTION BEGIN:
<code1>
[GENERATE YOUR CODE]
</code1>
# YOUR SOLUTION END: 

print(top_healthy_options)
pickle.dump(top_healthy_options ,open("./pred_result/top_healthy_options.pkl","wb"))

---END CODE TEMPLATE---

[YOU (AI assistant)]: Sure, I can help you with that.
